Sorry to thread hijack (sort of) but what is actually wrong with the game? I am meant to be getting it for Christmas on the PS3... is this unwise?
Really struggling to work out what is going on, but it sounds like Skyrim should be avoided until the New Year...
The PS3 version had a fairly big gamebreaking bug where if your file save got too big, then it became laggy to the point of unplayability. I'm not sure if this has been fixed not being a PS3 player myself, but if I were you I'd check that bug was fixed at least.
As for me, I didn't download the latest patch so my game is ok. I mean, I've had the odd bug/glitch here and there but nothing that has stopped me from playing the game completely, like that save file bug, or other not-gamebreaking-but-pretty-debilitating bugs like the magic resistance bork or backasswards dragons.
