Got this the other day. Most fun I've had with a sports game in a long time.
Finished my career as a HW today, going undefeated through to the end. My Lightweight fighter isn't having much luck. I decided to go to the league with the single 20-minute round, and I've been having a hell of a time, barely eking out victories in the dying minutes. My fighter has an enormous glass jaw and absolutely no stamina retention (the two places I'm obviously focusing my efforts at the moment), so that's the big issue. I just had back-to-back rematch fights that each went to the final minute. In the first one, I managed to catch a lucky break and start pounding out knee strikes in the thai clinch for the TKO victory. Second one ended a bit more on my terms with a step-up armbar.
Read that the sequel for this game is not a matter of if, but when. Quite pleased with that; I'll even pay full price for that one. EA Sports have sold me on this one.
(That said, when I went 40-0, I feel like a great section of the audience were saying "Yeah, that's all well and good, but how would he stack up in the UFC?" )
