Bought NCAA 12 for the first time in a couple of years, havent been playin any online dynasties but I have noticed that if you are playing someone online and they pause right after you make your kickoff selection at the beginning of the game the crap will freeze. I also noticed that sometimes it will go on turnover streaks and every time you touch the ball your guy fumbles no matter how little contact, got uber pissed when I turned the ball over 5 times in 5 series(4 fumbles, 1 pic) until it happened to a guy I played earlier today.
All in all I like it better than the lat one I had(09 or 10), in the old version you could literally run 3 plays on offense and not be stopped. Really like how they make the deep ball harder to complete so you cant just lob it up to a good reciever 4 times in a row and assume he'll catch 1.
