People seem to complain about the fetch quests a lot, except, all quests in all rpg's are pretty much fetch quests, name one quest in any game where you don't have to go somewhere to get/talk/kill something or someone.
Fallout 3 was nothing but fetch quests.
FO3 quest that were not fetch quest
Power of atom if u chose to blow up
megatron megaton
you gotta shoot them in the head
Moria's quest
Ridley's Rangers quest
the main quest
trouble on the homefront
Big town quest
and many others that i can't think of, note i haven't played FO3 for about 1 year and a half and i still remember them because they were somewhat epic, there aren't that many fun quest like there was in FO3
