^^ Well I completed all side quests but didn't discovered each and every location of the game. I think you also discovered each and every location of the game that's why it took a lot of your time. Or maybe you didn't used to use jump to location frequently because in most part of game I used that which saves a lot of time rather than walking there.
What were you doing in the game. Hanging out??? I mean man I completed the whole damn game with DLCs in less than 140 hours and was at level 30(max).damngoodman99 said:Fallout 3 + (all DLC's) - 423 hrs
Dragon age origins completing all side missions -- 214 hrs
