Picked it up last night and started a career. Only had time for one fight before bed, but after playing more today I'm now 5-1. Only had two fights go past the first round so far as well. I'm playing on advanced and...well, it's kind of easy. My career guy is a Muay Thai light heavyweight, but I can't figure out the muay thai clinch stuff for anything, so I mostly just take guys down, get a mount, and hammer them in the face until they stop moving or the referee pulls me off. At the moment I'm taking a break because playing my PS3 after not playing it for several weeks apparently gives me a carsick-like headache and I feel like hell right now.
Only buggy issues I've noticed so far is in my most recent fight, when I scheduled it it said it'd be main event and my opponent was 22 years old. When it came to the actual fight, it was the co-main event and my opponent was 27. No big deal, but still kind of odd. Another thing I don't like is that I can't figure out what the in-game date is.
