"Oblivion is everything this game should have been"
I disagree. Oblivion is a great game (dispite some HUGE flaws, still a great game makes up for them). But it's not really an RPG. I dont think oblivion would be all that great as a MMOG. I think it'd be a kickass multiplayer game, say 6 people max? That'd rock, but because the RPG aspects of Oblivion are minimalist at best, it wouldn't be that great a MMOG.
As I said below however, NWN2 is everything D&DO should have been lol, and then some. I just have to wait for september for NWN2 though
