I might have to end up buying a 360 version. I don't understand how it's so hard to release their DLC on PS3.
Its an issue with the shared memory system that the PS3 uses. Related to the slowdowns that many PS3 users had as their save file grew.
If you are going to get another version, I would recommend the PC version if you have the hardware to run it. The upgraded graphics and Steam Workshop alone are worth it. I had the PS3 version when it launched, and have since picked up a PC copy (Love the Steam sales)
