It's blowing my mind how people are saying that Sony is the only one with some sort of diversity. As if Nintendo and Microsoft only make games like Mario and Halo. Is it THAT easy to pretend that games like Animal Crossing, Viva Pinata, Fire Emblem, and Banjo Kazooie don't exist?
Everybody has some sort of diversity. Just because the other two have some sort of mega-franchise (and Sony does, too) that sells 10 million copies, that doesn't mean that's ALL they have. C'mon! I'd rather people point out that Sony always pushes for new formats (like they did with CD, UMD, DVD, and Blu Ray) or that Playstation has always been the home of blockbuster 3rd party franchises, or that they do their best to make sure Playstation owners aren't missing out on anything the other companies are pushing (motion control, rumble controllers, deep online). Settling on the "Playstation means diversity" answer is a little lazy.
For every inFamous, there's a Crackdown. For every Gran Turismo, there's a Forza. For every Uncharted, there's a Legend of Zelda or Alan Wake. All companies are all things to all people. Maybe Playstation has the preffered version of these genres?
