I never experienced any of the fabled "game breaking" glitches during any of the Elder Scrolls games, Fallout 3 as well. Had some cache issues, but after learning to hold A on startup early after release, things corrected themselves.
Just because you didn't experience them doesn't mean it's not there
In Fallout New Vegas people had corrupted saves after doing a particular quest and couldn't continue on after that. I didn't have that problem
To further exemplify the case:
I suffered that one. Greatly. It ruined Oblivion for me. :dead: If it's not in Skyrim, the game will be perfect!
