Similar to the Far Cry series, The Elder Scrolls games are just so massive and amazing that we tend to overlook little technical issues and glitches.
Most of these bugs don’t affect gameplay so they end up being more of a treat than a hassle, and others are downright hilarious. Because of these reasons, reviewers didn’t see the need to penalize the game’s overall score due to a few odd moments. Back when Oblivion was still a new game, the floating paintbrush was an internet favorite as were NPCs being melted into jelly when attacked.
The only serious bug was an unknown item that when equipped would completely crash the Xbox 360 but honestly, we can live with that in order this masterpiece of a game.
