who would win?

Assuming both galaxies are connected by some kind of inter-dimensional hyperspace tunnel so big, that any ship in either galaxy can simply plug in the coordinates of any location in the other galaxy and emerge there.

of course, neither side knows the exact coordinates of the most vulnerable/central/prizeworthy worlds of the other galaxy, so they cant rush the other side or otherwise we'd have everyone rushing Terra or Coruscant.

These are the combatants:

One one side, the Galactic Empire that has managed to crush the rebellion and is at peace. Possesses both death stars. Everyone in the troops is ready for battle. Only two jedi.

On the other side, we have the Imperium of Man minus the space marines. A galaxy rife with opponents like orks, chaos, eldar etc. No unity. But sheer limitless troops of the Imperial Guard and Navy at their disposal. Lets say for some fairness that the real threats (13th black crusade, major waaghs, hive fleets etc. have stalled and arent causing problems. We take this galaxy at its most peaceful state, minus the presence of the astartes)

Who would win?

Considering these types of threads usually devolve into "my setting is better than your setting!", I will give it to Star Wars for two major reasons.

One, the standard issue weapon in Star Wars is the ubiquitous blaster, which is a plasma/particle beam based weapon, which scales enormously from the smallest peashooter to a planet destroying superlaser.

Second is mobility. Hyperspace is extremely time efficient compared to traveling through the Warp. Imperial warships would be able to reach warzones in a fraction of the time it would take for an Imperium of Man taskforce to arrive.

This has been done to death in other threads. Not sure why you want to dredge it up yet again. Do some searching and you'll find a mix of thoughtful analysis and rampant fanboyism.

Neither 40k nor Star Wars canon was written to facilitate an apples-to-apples comparison. Both were written to make their respective empires menacing.

You can drive yourself mad trying to twist canon to make a comparison possible, but the other side can make similar arguments that are just as valid.

I am curious why you want to delete the iconic IOM troop type, the one that defines the 40k genre, from your scenario.

If you're serious you need to be far more specific about the timeframe and conditions of your conflict. The Galactic Empire at the end of the Clone Wars is pretty different from the empire at the time of Endor. 30k is radically different from the a Reign of Blood or the close of the 40th millenium.

Or you can just take a page from Stan Lee. "There's one answer to all of that. It's so simple, anyone should know this. The person who'd win in a fight is the person the scriptwriter wants to win!"

"These are fictitious characters, the writer can do whatever he wants with them! So stop asking these questions..."

Same thing goes for Empires and headcanon. Whoever you want to win wins in your brain.

Or you can just do what Screwattack has done with their Deathbattle series and play the head to head comparison for humor....

My two cents.

Because bringing in Astartes would completely tip the scales in favor of IoM, and I'm pretty sure past threads had included them. Lorewise an unarmed Astartes can take on 100 guardsmen. A fully armed squad can make short work of anyone, even Jedi. If you remember the order 66 scene in Episode III, there was this one Jedi who started getting shot at by Stormtroopers and he could only use his light sabre to deflect the first couple of shots before they went past him and killed him, so I doubt they could deflect bolter rounds as easily. The only time Jedi in the movies had an easy time deflecting shots was against droids (Episode II) but even then they took a lot of casualties. The presence of shielded destroyer droids could easily force a Jedi even the likes of Obi-Wan into retreat, so it doesnt take much concentrated firepower to bring them down.

Starwars wins over what ever Matt Ward wrote on toilet paper...

Well most of the Star Wars Expanded Universe has been considered non-canon so it does tip the balance A LOT

I have to give it to 40k tho, one reason is the Ark Mechanica (Mechanicus?)
The Ark mechanica is a Ship that is CAPABLE OF TELEPORTING ENEMY SHIPS THOUGH TIME IF IT MISSES SO THE WEAPONS WILL HIT IT

... and 40k has never had a canon, so...

If they can freely range through each other's space and don't have to worry about the other residents?

Star Wars. A single battle-cruiser can level a planet with sustained turbo-laser bombardment (as happened to Taris in the beginning of Knights of the Old Republic). This is Exterminatus-grade weaponry on basically every capital ship the Empire has, which can get across a galaxy larger than the Milky Way in a matter of hours.

http://www.dakkadakka.com/dakkaforum/posts/list/671762.page

16 pages says a draw.....

I say Star Wars primarily because of the massive speed advantage and the huge Navy advantage.

The Imperial Navy, at tis height, is supposed to have 25,000 Star Destroyers alone, not counting the thousands of smaller ships and fighters capable of carrying weapons powerful enough to damage capital ships.

The speed advantage is probably the biggest issue though. Assuming both sides are somehow restricted from altering their technology, the Empire is able to basically jump around the galaxy in hours rather than months. There are issues with this since the sense of scale present in Warhammer is completely ignored in Star Wars (flying between planets in a few hours without having a working hyper drive for example - Hoth to Bespin). In the new movie, there is almost no time between leaving a planetary system and arriving in another that is rather far away.

Why? They never get to do any fighting against enemies that arrive in incredibly fast starships and blow everything up. The Space Marines are just as dead as everyone else when their fleets and home worlds are reduced to dust.

Actually, looking at the older forum that Ratius provided, one of the key points was that the Galactic Empire has no hyperspace charts of the Imperium, which would make travelling via lightspeed suicidal. However, the Empires speed advantage would remain intact for fighting in their own territory, which would make any Imperial attack impossible.
Basically the Imperium will win in their own territory because the Empire cannot travel through it at lightspeed, while the Imperium cannot mount any effective attacks on the Empire. What I would be interested in seeing is how: 1) The various xeno's react (particualy Tau and Dark Eldar) and 2) what would happen if, while exploring at non-lightspeed, the Empire found a planet that the Imperium never found due to it being isolated from the warp tides or something.

Ewoks.

Is that supporting the Empire or the Imperium? Or are you suggesting Ewoks as the dark horse 3rd contender?

Again? Oh very well then, it seems fate has decreed there shall always be a thread like this. Maybe Star Wars vs 40k threads can be added to Dakka bingo?

Everything wins against the Galactic Empire because it has the worst trained army ever. Stormtroopers can't hit anything and all Imperial leaders save for Thrawn seem to be hugely incompetent douchebags. They lost to Ewoks for God's sake, before being defeated by a bunch of ragtag rebel scum.
In the meanwhile, the Imperium was capable of holding out against pretty much half of its armies and the AdMech rising up in rebellion. On the ground, it is not much of a contest, the Empire will be slaughtered.
In space, it is not much of contest either, if only for the fact that without proper navigational charts, the Empire's ships won't be hyperspacing anywhere. Same for the Imperium's ships without the Warp.

There are two ways they could map out the galaxy.

1. Get information from any of the denizens living here. For example, it is possible that the Empire first encounter the Tau, and strike a deal - information for technology.
2. Probe Droids. Probe droids would have to have some form of hyperspace travel, as they were, used to find the Rebel's secret base in Empire Strikes Back. It would then be a simple matter of releasing thousands of probe droids to map out the Milky Way.

As for Stormtrooper accuracy, watch Episode 4, when they board the Tantive IV. Stormtroopers enter through a heavily guarded checkpoint and not only do they inflict more casualties than they sustain, they force the Rebel defenders to fall back.

That says more about the Rebels being horrible soldiers than about the Stormtroopers being good. Seriously, they just walk into the line of fire without any cover whatsoever, without throwing in some grenades first or something similar. They present a slow moving, big white target in full sight of the defenders, without cover at a distance of just a few meters. And still the rebel soldiers can barely hit them. The fact that the Stormtroopers only took two casualties is entirely due to Rebel ineptitude, not due to the Stormtrooper's great skill at stumbling around in hallways.

By conservative estimations, the 40k Imperial Navy significantly outnumbers the Galactic Empire's navy. Not to mention the smallest 40k escort class vessel is larger than a Star Destroyer and has far more devastating weaponry.

25,000 Star Destroyers is rather pitiful, and the smaller ships are going to be even more useless.

Literally the only advantage Star Wars has is that their FTL is faster. In all other areas they are inferior. They are less numerous, carry less powerful weapons, and are less durable.


Then there is the following problem. The Star Wars universe is, to put it bluntly, full of incompetent individuals and weak willed people. The Empire/Republic only had a few million soldiers at their greatest numbers, yet even with this very tiny numbers they were still capable of maintaining a moderate amount of control over their galaxy, yet they were also overthrown by a few thousand poorly trained and equipped freedom fighters.

This tells us that nobody in Star Wars really has the stomach for actual warfare. The civilians are so cowardly that they can be controlled with barely any threat at all, and the soldiers of the most powerful faction have never actually faced up to the horrors a truly galaxy spanning conflict against a foe who doesn't pull punches would unleash on them.

Any fight that Star Wars gets sucked into is going to be a bloodbath. The difference is that the Empire would not be able to sustain their numbers OR be able to maintain good morale. The Imperium is more than happy to throw troops into the meat grinder because they have literally infinite manpower. The casualties would absolutely horrify the Empire's soldiers as they got overwhelmed with sheer numbers, and an opposing warmachine on a scale they cannot imagine.

Given the input from the latest commentators, I personally think that what would happen is that the empire would have to start fighting like the rebellion. In blunt numbers and firepower, they are horribly outmatched in everything, even without Space Marines present. The imperium has many more ships which are both larger and more powerful, and on the ground the Imperium has the sisters and the death korps/catachans/other over the top guardsmen, compared to the Stormtroopers, the 'elite' of the Imperial military.
As a result, the Empire would probably end up hiding and using their superior mobility to keep hitting at the imperium's flanks, similar to the rebels . Unfortunately for them, the Imperium has no 'death star' equivalent, and their is no way for them to destroy the Imperial command like the rebels did in Episode VI, so even if it took a few decades/a century, the Imperium would win through their sheer unending manpower.
I am interested by the idea of the empire meeting the Tau first, especially if it was Thawn leading the Imperial force. That could be equally interesting and Hilarious.

Another note on the storm trooper/guardsmen comparison, do we know how the basic blaster and lasgun stack up next to each other? Given how flashlights are considered in the 40k setting compared to blasters, if they were the same power then SoB would be effectively invincible (if only they wore helmets. still, that may just make the Stormtroopers aim worse).

Terra. Destroy it and the Imperium loses most FTL travel and according to some background every human being becomes a gateway for Daemons (due to the death of the Emperor).

true. But the Imperium knows that this is their only real weakness, and I was under the impression it has a freaking huge fleet there at all times from previous Imperium vs X forums.
even if there was no fleet, the Imperial Palace isn't exactly the easiest thing to break into. Ask the Iron warriors.

Star Wars doesn't have the firepower to destroy Terra. It possesses the most powerful void shields in the Imperium, and we already know that void shields are strong enough to shrug off Exterminatus.

Correct, the Imperium doesn't have the equivalent of a Death Star. They have something far more effective, because they're not stupid like the Empire. They have Cyclonic Torpedoes and Virus Bombs, and almost every ship has continent leveling firepower just from its conventional weaponry.

The Empire had one station which could destroy one planet at a time. But any Imperium ship with torpedo tubes(which is the vast majority of them) can kill a planet if so desired. Even one virus bomb is certain doom for any planet, more just makes it happen faster.

The Death Star showing up at Terra would also get destroyed long before it got into firing range. Its the perfect target for the Imperium to deal with, large and slow moving. Alternately, the Imperium simply swamps the Death Star by teleporting thousands of troops inside it. They take control of it before it can fire and now the Adeptus Mechanicus has a new toy. A few years later a "new STC" is discovered, and now the Imperium has Hyperspace drives and Super Lasers mounted on their ships.

that is a good point.
however, what I meant by "the Imperium has no death star" was that there was no renowned unique superweapon that the empire could group up, ambush, and destroy the same way the rebels did to both death stars, hurting the enemy and drastically affecting their morale.

This is also a real good point. The Imperium of 40k really has quite a lot of leaders, and good ones at that, and taking one out does little to slow the machine down. If Creed goes down, Calgar steps in, if he goes down, Grimnar steps up and so on, so on, so on...

The Galactic Empire, on the other hand, really seems fragile in this regard. Aside from one or two powerful figures at the top (Palpatine, Vader), the leadership seems only adequate at best, and incompetent at worst. It doesn't help that folks like Vader are quite happy to kill those in command and further disrupt organization.

Someone asks this question once every so often and the answer is always the same.

A Star Destroyer is about the size of an Imperial frigate in 40k. A Super Star Destroyer is slightly bigger than an Imperial cruiser. On top of the size differential Warhammer cruisers are perfectly capable of cracking a planet, something A New Hope implies is far beyond the capacity of the entire Imperial fleet shooting full power at one planet. The Battlefleet Gothic books suggest that, among other things, Imperial ships are capable of combat at ranges orders of magnitude greater than anything we see in a Star Wars movie, with vastly larger and more powerful weapons.

So if the two settings ever ran into each other half a sector battlefleet could probably take the entire Galactic Empire to the cleaners. If you want a less one-sided crossover try Star Trek, where the ships are under half a kilometer long and can still crack planets by themselves.

My comment had nothing to do with tactics. It was pointing out that your comment about Stormtroopers never hitting anything is clearly false. The only time they ever seem to miss is (surprise) when shooting at the main characters, who naturally have plot armour to keep them alive.

Super Star Destroyers are 19 km long. How long is a cruiser? Hint it is less than 10 km.

A New Hope does not imply that the entire fleet could not crack the planet. It implies that the entire fleet could not cause a planet to violently explode in such a short time.

Assuming when you say "Star Trek" you are referring to just the UFP, Star Wars would crush them. Not only would a troop transport be able to destroy the Enterprise one on one, the Slave I could do it. And that's a 1-pilot patrol ship.

So? Never hitting anything is hyperbole of course, but that does not change the fact that Stormtroopers are notoriously bad at aiming and are horrible soldiers. Far worse than the battle droids from the prequels even.

Yeah, Super Star Destroyers are huge, but there is only a few of them.
Here is a good comparison chart for Star wars and 40k ships:

Ships in Star Wars are indeed capable of pretty devastating planetary bombardment and have no problem wiping out entire planets, though their weapons are not so devastating as those in 40k.

I don't think any ship in 40K has demonstrated the ability to shatter a planet into an asteroid field in a few seconds. For all we know Death Stars do have the capability (let alone that new Sun Killer thingy) to breach Terra's void shields. Either way, the second Death Star was shielded so well the Rebels didn't have a chance of breaching it (and that was when it was unfinished).

One of the Death Stars had force fields. I'm not sure teleportation would work through it even if it is totally different technology to void shields (can you teleport through Tau forcefields?).

Yay, this thing again! Oh god...
So, we assume the galactic Empire (GE) during its peak had about 25 000 Star Destroyers. Each Star Destroyer had about 10 000 Stormtroopers onboard. 25 000 times 10 000 equals 250 million Stormtroopers.
Add to that about 500 000 AT-AT's, 750 000 AT-ST's and 625 million Enlisted soldiers you have a formidable army.
More than a billion soldiers, and a million vehicles! Wow! It seems impressive until you realise that a single Titan Legion contains 1 Imperator Titan (aka New York, but with HUGE FETHING GUNS THAT WILL BLOW YOUR HEAD OFF BUT INSTEAD IT'S A HUGE ROBOT), 1-5 Warlord Titans, 5-10 (!) Reavers and up to 20 Warhounds.
Then remember that there are 40 Legions mentioned on the 40K Wikia, but I'd estimate there being a few more.
Then you realise that there are hundreds if not thousands of IG regiments, with many in the tens of thousand of troops, and possibly the same amount of tanks.

Ground forces only? Imperium wins.
Space? Empire wins.

Super-star Destroyers are larger than 40k battleships, however they were always very rare and their weapons aren't any stronger than a normal Star Destroyer, just more of them. And they'd again have the same issue as the Death Star, a huge and slow moving target.

Plus their shields are demonstrably not all that powerful. Remember a single A-wing crashed through the bridge of the Executor, which totally crippled it and caused it to crash into the Death Star II. Which tells us that Star Wars ships don't have back up navigation control or redundant command areas. They have a single bridge which is exposed to the outside of the hull, unlike 40k ships whose bridges are deep inside the hull where they are safe, with only the sensors being exposed on the outside of the hull(which is true of any space ship).

The reason that you cannot teleport through Void Shields in 40k is because Void Shields use the warp. They transfer any incoming objects and attacks into the warp itself, this also makes using Teleportation(40k teleporters are essentially short ranged warp jumps) impossible.

As Star Wars shields are some form of energy field, they would not prevent 40k teleportation.

IIRC Tau forcefields are reverse engineered void shields, similar to what they did with a warp drive to get their current FTL drives, thus they function on the same principle and block teleportation.
