Spacesims have a good chance on the consoles I think. Most of the modern pads come with a stick build in so no more excuse for "we don't develop them because people would have to buy a joystick" Beside that extra preriferals are in. Every game has it. Just can't wait till "Cockin' with Mom" has an "authentic cocking pod."
Anyway I agree with Zane, that pop culture has a heayv influance on what games could sell well. Just think about the Halo hipe. I mean I found the first game terrible when it came to the PC but still I was watching the news about the second and third title because everyone talked about it.
