there's unlimited fetch quests and skyrim had about 250 regular quests for the base game not counting dlc, just dawnguard alone had a good number of extensive quests and they were hardly fetch quests, and the same for all the faction/town/mainquests they weren't fetch quests, it takes hundreds of hours to do all skyrims quests, here's the link to all the base game quests http://www.uesp.net/wiki/Skyrim:Quests
fallout 3 was a different story all together, exploration was what fallout 3 was about, i wish it did have more quests but it still had a lot do and the quests it did have were good.
