Neither do. Good games sell platforms. Even better if they're exclusive and you can't find that experience any place else. Basically, you need a killer app. Who makes it is irrelevant.

I agree that AAA games have the marketing power to broaden appeal. However, indie gaming is becoming a powerhouse of sorts. Look at the Steam Top Sellers list at any time, and you'll usually see at least half the games listed there being indies. Currently, it looks to be a solid 50/50, although I'm sure the residual affects of the last Steam sale are there.

Something with the viral appeal of Minecraft, released for the Oculus, would be a massive draw.

Bought PS3 to play Journey :) Worth it.
