I am quite the opposite, I loved the earlier fallouts, and I also loved Oblivion, however, FO3 is very different from the earlier FO's, and I can see that by doing what Bethesda have done, i.e. tried to make FO3 appealing to those who liked the earlier ones, and also try to appeal to a different demographic, have probably alienated a section of those people who liked the originals.
To me, FO3 is a very different game from FO1/2, I think it works well, I don't like FPS combat, so the addition of V.A.T.S is good for me, I don't really think of FO3 as Fallout 3, it's a different game set in the same "world" as the previous FO's, rather than a sequel.
