http://www.dakkadakka.com/dakkaforum/posts/list/69.page JForum - http://www.jforum.net GW has been slowly increasing the size of their models over the last decade and with that size creep has come larger bases as well as shape swaps. I'm not entirely clear on how base size and shape affects everything in 9th, but I have read enough to know that it seems to have an actual effect on gameplay, possibly even a significant one. So here I am with a lot of old models with different base sizes than their current equivalent and am trying to figure out if I need to be worried about the older scale models having a distinct advantage or disadvantage for having smaller bases (and being a smaller model over all). I've heard some argue that they are fine with old models running their original smaller bases because it's a disadvantage in some situations, but I've heard other argue that it's actually an advantage in other situations and shouldn't be allowed. As a casual player, I'm not as concerned with this as competitive players might be, but I don't exactly want to hamstring my armies by using smaller bases than the current standard. On the other hand I also don't want to be accused of cheating because my models have smaller bases either.

For example, I have some of the old 3 piece metal Terminator models from the early 90s. These have slotta tabs and were originally intended to use the standard 25mm slotta bases of the time. Now however, Terminators are supplied with 40mm bases. I don't really want to go through the trouble of finding reasonably priced 40mm and rebasing them, partly because it's expensive and takes time if I want to actually do basing detail on my army, partly because I don't want to chop off the slotta tab as I feel it's part of the model and should stay, and partly because I feel they would look silly on the larger bases since they are smaller than current models. There are plenty of other models in similar situations, like my old CSM Bikes on the old cavalry rectangle base.

My best idea for a compromise on models that merely went up in base size is to copy my plan for old IG heavy weapons and double base them (leave them on their original base and simply stack them onto the new size, likely with some sort of basing effect and magnet to make the new base a tray of sorts instead of actually gluing them on. Alternatively, get some custom 3D printed bases with built in depressions for the old bases and make it literally a tray so as to reduce the extra height from two stacked bases), but it's not so easy with shape changes such as the bikers rectangle to oval.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985187.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985187.page GMT
Except the bikes. For me, an army needs to be all on circles/ovals or all on squares and a mix of both is just wrong. It makes me cringe just thinking about it. I would definitely rebase the bikes. But that's just me.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985191.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985191.page GMT
GW doesn't have any rules about base size other than "what the model comes with". So you are perfectly fine to use the old metals on 25mm bases. I've upped mine to 40's, but they look strange and lost. I might go back and do 32s or 30s.

It really only matters if a tournament is going to strictly require certain bases sizes, or your opponents are going to have a problem with them.

There is no super advantage, and even some disadvantages, to smaller versus larger bases sizes (and vice versa). As far as I've seen, it all evens out in the end. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985198.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985198.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985316.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985316.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985361.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985361.page GMT GW says otherwise.
My entire RT Salamanders force is on their original base sizes and they're not gonna change just cuz some donkey-cave says they aren't "legal".

Save money and buy more models!]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985364.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985364.page GMT
If you're playing heavily in tournaments, and the TO require the current standard, just blu-tack your dudes onto some carboard "bases" (or go whole hog and some thin magnetic "bases" and magnets ala a carrying tray) to match the current size, or invest in some snap on converters if you want.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985402.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985402.page GMT
Tournaments might require certain base sizes.

If you're not a tournament player, leave them as they are.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985426.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985426.page GMT
As someone who got hooked on the lore of 40k after being introduced to the universe with DoW DC, I've always been a more casual player. I doubt I'll ever want to play in an official tournament unless I somehow get enough 40k friends to host a friendly "in-house" tournament so to speak that's big enough to meet whatever GWs requirements are for a tournament to be official. Even then, the only reason to go through that trouble is if GWs hands out official goodies or some such if they recognize the tournament. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985581.page http://www.dakkadakka.com/dakkaforum/posts/preList/793926/10985581.page GMT
