WARNING: The latest updates crash the game. Play single player without crashing / loading problems by canceling out of the update process when the game starts. I think it disables the online features but I never used those anyways.
The gameplay was awesome once you got past the glitches but the glitches really hold it back. The update I downloaded caused the game to crash. I deleted all the game data and tried again without updating and it worked fine from there, the game didn't crash but there were still a few glitches in the gameplay that held it back.
It just seems like they didn't take too much time to debug the PS3 version but the game has a lot of potential, it is really cool what you can do and driving around the city was really fun. I would have given this a 10/10 if it hadn't had problems.
