I put 12 hours into it in 2 days and have been hesitating on taking new missions because I just don't want it to end. A friend and I messed around in co-op for a few hours and it was a blast. I'll probably only put a couple hours in over the next couple days, but will surely finish it over the long weekend.
Took me 25 hours to get 100% not including stealing all the cars. That got me up to level 50, which was really helpful for the last few missions. That makes it 4 times as long as mw3 which I should have rented.
