IMO Fallout3 is Oblivion with guns. Though the F3 world is dulling and depressing, it's actually a bit more interesting and applicable to real life. While Oblivion has a brighter world, there's a lot more space of nothingness than F3.
And yes you get encumbered in Oblivion like you do in F3. Honestly if you don't like F3 I doubt you'd like Oblivion. But you need to give F3 a fair shot before you write it off. You mgiht eventually like it, and Oblivion as well.
