I must be lucky as I never get any of these crazy bugs when I play games,perhaps it's because I play a lot of games some time after release and they are all patched up.I mention this because I just recently finished Skyrim for the first time and was expecting some weird stuff.....but after a pretty long play through I got virtually nothing.
I swear my copy of Skyrim was actually bugged though because all I'd ever heard about the game was "I used to be an adventurer too,but then I took an arrow to the knee"and I honestly don't think I heard that line more than like twice in my entire playthough......"never should have come here"however,about ten times in every encounter,lol.
