I think the middle design has the strongest composition and most eye-catching colors of all three. I do agree with RaNaeNae's advice to include "Ace Pilot" in a more straight-forward font somewhere on the poster.
Also, it would probably clash with the visual aesthetics, but you might even consider slapping one of those fancy square bar code things on there with a link directly to the game. QR codes? I think that's what they're called. That way, you won't have to worry about anyone remembering anything. They can just scan it and save the address on their smart phone.
i'm definitey doing one of those bar code things. i don't know about the necessity of making ace pilot in more generic font somewhere in the poster though. i'll play around with the idea.
Can anyone say...
