This is irrelevant. It is a game review, not an RPG review. I know all of us here will be somewhat biased, but still… I, for one, have not had Oblivion corrupt a save game (for example).
NWN 2 is a decent game (and better than Oblivion IMO) in concept. Oblivion is a better game in execution. Maybe not 150% better, but on the whole the review is fair. As the man says, patches will change things.
