I've been playing the game for a few days now, I think I have about 32ish wins in my lightweight career. It just now started to get difficult. I just had a fight go all 12 rounds for the first time. It was a pretty intense fight because I went for the KO early but ran my stamina low and spent most of the fight recovering.
This game really boosted my gamerscore quick. I think it's amost 4000 now
