The initial release of the game was just plain crap. After 1.4 things got a lot better. And with 1.7 I've gone back to having a dip in frames, and some stuttering on occasion, nothing too annoying. If you're going to purchase it, then get it used for the price difference. If you already have it, I don't think it will cause your console to explode now. BTW I play on a Slim 160Gb PS3. With all that said, I really have enjoyed Skyrim, and it's worth playing, just don't expect a polished game.
Also I don't have a fishy stick, but someone will get you one. Welcome to the Forums!!
