I played it on the 360 and I didn't really find a lot of glitches. There was the very rare being stuck in geometry moment, but other than that nothing game breaking. There were people that complained about it freezing and crashing every 30 minutes, which is one of the main reasons why the review scores aren't that great, but that never happened to me and I think it was fixed with a patch. Overall a great game, if you liked Fallout 3, you'll definitely like New Vegas. The beginning isn't as good, but the world and characters you meet are much better in my opinion.
