Completed career mode on pro difficulty yesterday. It's ok but feels kind of lacking really. There's really not much content there at all. Gets very repetitive. The AI isn't good enough to make it fun or challenging either.
One thing that annoyed me is the opponents it kept giving me. Like seriously I was heavyweight champion, around 30 wins and 2 losses, 15+ fight win streak, 15+ knockouts in a row, and it's making me fight these randomly generated fighters constantly. I was expecting to be fighting Dos Santos, Overeem, Velasquez...etc. But no. It even made me fight the same 2 people something like 6 times in my last 10 fights. Didn't fight one actual big name in my last 10-15 something fights, just random boring create-a-fighters.
That's another thing. It automatically retires you after 40 fights. So what's the point in the career damage/longevity system?
