UFC 2009 Undisputed is, by all accounts, a pretty great fighting game. Realistic, too. But there's one thing missing from the game: renowned fighter Clay 'The Carpenter' Guida. And his giant hair.
Believe it or not, Guida - who has an enormous lion's mane stuck to his scalp - was left out of the game due to technical concerns over his hair, which was causing major clipping and collision detection issues. Indeed, things apparently got so bad that THQ, the publishers of the game, offered him cash to cut his hair in real life, so they could trim his in-game model.
But Guida refused (good for him!), and so had to be left out of the game, because his character was borderline unplayable.
So there you go!
