Yeah, but you have to remember that those are things that go with the Fallout series style, not the TES series style.
Excuses!
Still, ~60 quests...
I just counted quests. Here are the results:
Fallout 3: 67(without DLC)
Fallout 2: ~130
Oblivion: ~230(without SI)
I hope you're right, but for quests, I can't predict much, other than TES V having more than Fallout 3. Will TES V have less than Oblivion, more, or the same amount?
