The demo is great, but there are some issues:
1) Submissions are way too hard to pull off. I rocked Liddell from inside his guard then went for a kneebar, however, he STILL managed to escape. He wasn't fresh either, this was in the third round.
2) Mouthguards fly out TOO often.
3) Mike Goldberg says "Murillo" Shogun Rua, instead of Mauricio.
