I started with Super Nintendo as a Kid.
And for a good long time Microsoft Xbox had me won.
But hands down, for the last four or so years. Sony Playstation has had my vote because I get left the eff alone if I wanna be. Nowadays the Wii is for Parties, the 360 is for hardcore gamers jacked on Call of Duty and Gears of War.
The Sony Playstation 3 has tried its best to market into multiple players with the Move and Playstation Online. But when it comes down to it the only players that matter are players one and player 2.
I digress however because I have yet to enjoy the upcoming "Playstation All-stars". And I wait to see if it keeps up with Super Smash Bros. Or if its just another knock off like "Cartoon Network: Punch Time Explosion".
