Question is in the thread title: Would you still buy and play X-Wing if the ships came unpainted?
The question is strictly on painting, everything would already be assembled to the same quality as they are now - just without the paint.
Would you still pay $15 for the basic expansions if they were unpainted?
Would you be happier/more satisfied if expansions cost less without paint jobs?
Would you still enjoy the game if the ships were not painted?
Me, personally, I really appreciate how FFG can price the products so well, especially with the paint jobs. However, I feel like the paint job is just the icing on the cake. We already get FANTASTIC models, the game is fleshed out and successful and their goal of providing everything needed to play at such a low price is respectable for a miniatures game. If the ships came unpainted, I don't think I would have any grief.
For example, IA does not have painted miniatures, but they're still pricing their relatively-sized expansions similarly to X-Wing and it's still popular (I think). I think unpainted ships in X-Wing would benefit people who enjoy the hobby aspect of the game, those who are willing to spend the extra time and money to paint their ships, but it could also benefit the gaming aspect if ships were unpainted and the expansions cost $5-$10 less because of it.
Now, I have no idea whether or not FFG would sell unpainted ships, I'm actually 100% certain that they wouldn't even entertain the idea. But, in an alternate world where X-Wing's franchise was sold unpainted for cheaper or at the same price, would you still bite? Would it still be as popular?
