Great review, that was easy(and fun) to read.
I agree with the statement that Fallout 3 is better than Oblivion, and that the games are quite different(i.e. Fallout 3 is NOT just a re-skinned Oblivion with guns). But I felt that it was to few quest in the game overall. There were like 10 main quests and another 10 or so side quests, and neither of the quests took that long, really. Not to say that I think it lacked content(I made 3 characters, each with more than 40 hours of gameplay), but unless you wanted to explore the Wasteland without any real reason, you wouldn't get a very long game.
But then again, Oblivion had a lot of quests, but they were often repetitive or grind-ish, so maybe it was for the better...
