I specifically said AAA game, of course if you'll look at smaller titles or older ones you'll find lots of hilariously bad examples of VA that are much worse than oblivion. BUT compare Oblivion to AAA games that came out around the same time(let's say GOW3, FFXII, MGS4, ME/DAO(a bit later than oblivion) just to give a few examples from different genres) or even to any other bethesda game that came after it including published ones and you'll find That Oblivion VA is just awfull in comparison, not just worse but MUCH MUCH worse.
Of course in the end to each his own I guess, I just felt the VA was one of the weakest aspects of that game.
