LOVE crackdown. Played it long enough to get 1250/1250 achievement points.
The game is just incredibly well polished. I don't really remember any glitches, the in-game achievement list that shows progress etc etc. It's clear they spent a huge amount of time not only making a good game but then ensuring it was polished.
Tbh I wish there was more DLC for crackdown or a sequel. The game is just so much fun.
