If you had asked me the very same question five years ago then I\'d definitely say Square. But ever since FFVII, they\'ve...well... sucked major llama anus im my opinion. The only Square game I\'ve enjoyed since FFVII was Vagrant Story.
Well, right now I have to say Rare. They can pretty much develop a great game for all genres. For FPS, they\'ve created, IMO, the two best FPS ever with Goldeneye and Perfect Dark. For platform games, Banjo-Kazooie is neck and neck with Mario 64 for being the best 3D platform game ever(don\'t start with the Crash series Sony fans, you know it sucks!
). For racing games, they\'ve created a pretty good and innovative game with Diddy Kong Racing.
Jet Force Gemeni was a pretty good third person shooter. And most TPS suck...
And they\'ve proven they can break new grounds with fresh and innovative killer titles like Blast Corps and Conker\'s Bad Fur Day.
In conclusion, Rare rulez and Square droolz.
