Skyrim's my GOTY. Like others have mentioned, I haven't experienced many bugs. I did run into one bugged quest, but there's so much else to do in the world I just walked away from it and haven't thought about it since.
Now, if I ran into a mission-breaking bug in a game like Uncharted or something, that would mean Game Over, because those games are linear, have only one possible main character, one story, then it's over. But in Skyrim, or any TES game for that matter, a bug or two aren't nearly as destructive as the same things would be in standard, run-of-the-mill games.
I would rather pay $60 for limitless hours of content than for one short, linear story that has no replay value. (Not talking about any game in particular there, just in general).
