Personally, I've never been a 'fanboy' of any console. I always just bought the ones that had the games I wanted. For instance, call me a picky gamer but I NEVER wanted any of SEGA's game consoles unless it had at least one good Sonic game in its library, which is why I never wanted a Saturn. xD Despite playing lots of PC games, I prefer a game console whenever possible. SRB2 is the only game I have that I can't play on a console, so the Gamecubes needs to be dusted every once in a while. xD
I guess you could call me an Nintendo fan, since most of the games I like are on Nintendo's hardware. I honestly don't find the 360 or PS3 interesting, although I might get a 360 if the price drops any lower, but the Wii comes first!
