Well every platform has exclusives, it's just that Nintendo exclusives are the ones I actually want to play since most AAA's nowadays are just so stale. $400 might be unfeasible, but you can quite easily build a very decent entry-level gaming PC for $550-600, e.g. with an FX-6300 & R9 270X, that'll provide a better gaming experience than either of the new-gen consoles for the entirety of their lifespan. And the money you save on games and online subscription fees in the long run will more than make up the difference in initial investment. This is what I helped a friend do earlier this year, and he's using the money he saved by going the PC route to get a Wii U. And the rumor on the street (from AMD no less) is that the PS4 and Xbone are gonna be refreshed much sooner than people expect because of how anemic the hardware inside them is.
