you are a moron.
I played for almost 20 hours straight with one single glitch, and guess how I did it...i didn't buy my game from steam. fixed.
all of you people are seriously stupidly funny with your cries of doom and hate making up all these stories of "bugs" to have something to whine about. oh no you bought the game from a crappy distributor who hacks up the code in ways it wasn't meant to in order to make it proprietary to their client....it's not bethesdas fault you decided to buy it there instead of from a distributor that gives you a clean copy of the game.
Without me having to match your language - did you pay attention to your installation?
You might have noticed that steam is used on those CDs as much as it is from steam purchased copies - its the DRM method used for this game
Any "Hacking up of the code" is equaly required in your game as it is everyone elses. And since Bethesda and Obsidan decided to use steam, then guess what - the code is meant to be hacked up that way
That also doesnt account for console glitches, or the glitches that reviewers have (I presume they're sent steamless copies?)
Bugs and glitches are always going to be a hit and miss thing - some people will have them, some will either not, or not notice them.
