The right answer if you are a nerd is Baldurs Gate 2. It is like HL2, not that good, but held in legendary regard.
I would say Dark Souls, because for some reason that is thrown into the RPG genre even though I would not consider it an RPG. The combat is excellent and there is no story I have to slog through to get to the sweet, precious gameplay. Its multiplayer adds on short term replay value and its "difficulty" adds on long term replay value. The game has a fucking SHITLOAD of problems, but I don't think I have enjoyed an "RPG" as much as I have DS.
