I have literally had not one bug on the vanilla version. Not one. Not even something small like a floating plate or anything. Is everyone seriously having that many issues with the vanilla?

Good for you. There are a few lucky ones out there. Question: How big is your save file and what level is your character? Not to sound pessimistic, but maybe you just haven't experienced the bugs yet. There have been many that have come on these forums that have a first post very similar to yours. A week to a month later, they are right next to us watching their game glitch up, freeze, and crash.

To answer your question;

Yes, there are thousands that have had way too many issues to mention. Add to that the lack of DLC, the lack of any real communication from Bethesda, and the fact that they seem to treat the PS3 console as an afterthought and a money grab and that explains why the forums here and other sites are full of anger and rage.
