I feel like this question is really asking "What is stopping you from buying into another system?"
I think most people here would try something if you handed them the rules and the models/playing pieces. We're all gamers. That's not the issue, or the thrust of the
TC, I think.
Nothing has stopped me from buying into new systems. I bought into Flames of War in 2008, and so far in 2009 I have bought into two games, Star Wars Pocketmodels and
AT-43.
Last year a friend convinced me to start Flames of War. I was very skeptical. It was going to be about $350 to start it off with a 1,500-point army (I go all in or not at all), but he didn't want to play the Germans as he's Jewish and needed someone to join in, and he's a buddy so I bit the bullet and said "What the hell."
I can't say we got lucky, really, because
FoW is a superlative game. I prefer it over anything else I've ever played - but I can't say I'd done much research beforehand, I just like
WW II history and therefore loved the models. Turns out the game is awesome, and now 10 people in my club play it with more looking into joining us, so now the investment feels justified. We're even cranking out 15mm
WW II terrain and people are discussing their second armies already, moving from Late War to Mid-War Africa.
With the Star Wars Pocketmodels, I just love Star Wars, and the same buddy was playing that, and so I picked up a bunch of them cheap online...then played the game and instantly hated it. Again, I bought in because I loved the little styrene ships, and what a novel idea. I wasn't aware of the Pirates game until after I got my hands on the Pocketmodels, but the idea of little push-together styrene ships seemed awesome.
Game sucked, am almost done selling everything. Friend has his crap in a tupperware container somewhere.
With
AT-43 I was the insitgator on that one, mostly because I love toys and here were toys with rules and everything was dead cheap online. Bought three armies with the intention of pioneering the game at my club, my buddy from
FoW and the PocketModels joined me (my turn to cost
him some money, I decided!), played a bunch of games with each army I had, he dropped out after one marathon gaming session because he hated the rules, another friend bought a Therian army and during his second full game actually wanted to walk away from the table, and the most reaction I got out of people at the club was "Wow, those containers are cool."
I also decided the game sucked, and now am selling everything except some of the shipping containers which I am repainting to be Imperial Guard terrain in green with Imperial Aquila in tune with the upcoming Planetstrike expansion. Something good came out of it.
AT-43 terrain is easily re-painted and re-purposed for
40K.
So, in buying into new games I went 1 for 3, which is a bad enough percentage for me NOW to be gun-shy. What will stop me from buying into another system? Fear that the game might suck, the need to purchase models or playing pieces to find out for myself, and lack of a sizeable player base.
If I ever
think about buying into a different game again, I will do the following:
1) If it is a game I am considering pioneering I will find
every review utterly
trashing the gameplay. You learn much more from negative reviews than positive reviews,
IMHO. My wife never buys any item of clothing, piece of electronics, or makes hotel reservations for us until she's seen every a-hole ripped into that item or place that anyone could rip. Then she decides. If you can't find too much negative info, then it might be worth it.
One lesson I have learned in regards to negative reviews is that if you really can't find ANY then it probably means that only the fanboys are talking about it, and that tells you something in and of itself. You can find pages and pages of people ripping apart
40K and
WHFB gameplay because so many people have played it - so you know that the game has spread far and wide and that the player-base is large.
2) I will see whether I can get my hands on the models from someone else, and not just for one demo game, but someone with a DEEP model collection for an army who can lend me a book so that I can try building armies myself and see what I think for many, many games. If the gameplay is good enough to keep me coming back for more demos, then I might be onto something.
I won't decide whether to buy into a game ever again until I've been able to test its depths of gameplay and give myself ample time to find all the problems I can find.
I don't mind spending time playing a new game because it puts the existing games I play in a different light, and helps me appreciate their good points more. As a result of playing
FoW, I appreciate the speed with which a
40K game goes. As a result of playing
AT-43, I appreciate the superlative quality and the rules support and the player base that
40K gives me.
I do mind having to spend my money to learn that a game sucks for me.
If I cannot find someone with enough enthusiasm for the game to own multiple armies, or someone willing to bring someone else along with him while he lends me his armies, then that will speak to whether there's a player base, which brings us to...
3) I will see how large the established player-base is.
My intention in purchasing three
AT-43 armies was that I would be demo'ing the game to people and hopefully getting them into the game. I won't ever do that again. Trying to start up a community around a specific game system is a massive pain in the ass for me, and I have better things to do with my time. Like posting on message forums.
I also am not willing to keep odd hours or travel long distances to find opponents for a new game. I could wake up on Saturday mornings at the crack of dawn or travel an hour+ straight from work once a month to get
AT-43 games in and have a bunch of opponents, but that begins to become work to go so far out of my way just to play a game. I have a feeling that any niche system is going to require something along the same lines to find opponents for it.
My gaming club meets on Thursdays, and is huge. If enough people there play a game, I will look into it. I've never played
WHFB, and plenty of people have armies to lend me. I'm not interested in painting up fantasy stuff but I would learn the game as most people play it. A bunch of people play Warmachine, and it seems like a pretty popular game, so if people lend me books and models I'll try that, as well.
