When I started to play The elder Scrolls IV: Oblivion and put about 20+ hours in the game I started to notice bugs, and I mean big bugs ones that had something to do with the main quest. I tried really hard to over look them but couldn't. At the end the hole game turned out to be a big bag of shit and look at The Elder Scrolls V: Skyrim. This video I found wasn't on YouTube at the time but I managed to fine it.
