Talking about Oblivion or fallout 3 you REALY need to talk about what mods you want to include, because especialy in oblivion case, the game ranges from good up to near-perfect depending on the mods you install and how you set it up.

D2 ofc doesnt have that amount of modding yet since its too new (even though there's already an HD texture pack around)


About the glitches, larian already promissed a patch soon for those. Don't forget that for example the Gothic series was almoust impossible to play in the beggining, and after a couple patches (official and community) the game is now on the all-round classics of a lot of people, same with Vampire:Bloodlines, etc (just to mention some RPG old classics).
