I made the exact same mistake. When I finally got the Fallout 3 DLC on the PS3, I had even more problems than I had with the vanilla game. No joke, you know those derelict cars in Point Lookout? They were doing somersaults on my screen. It was like being at the circus, only in a video game. Fallout New Vegas? Even worse. Multiple crashes during loading screens, tons of headaches with corrupted saves. Granted, I have those same problems on my 360 copy, but not nearly to the same degree. After making those mistakes, I also concluded that Skyrim was a better buy on either of the other two platforms. I'm not trying to start a console war or anything, just trying to bring awareness to the fact that this team, nor Obsidian for that matter, can seem to handle the PS3 platform. The only thing I can recommend is to change your platform if you love the games that Bethesda makes. I know I do and I couldn't let my experience on the PS3 get the best of me, so I changed platforms. Like I said, I'm not trying to start a console war, only trying to tell you guys what your best option is if you want to play the DLC. Even if you guys got it, and if it is anything like their DLC for Fallout 3, you WILL NOT want it. Somersaulting cars is hilarious, but ridiculous (also crashes your framerate).
