Yeah, the Gothic games are the gold standard for NPC behavior in RPGs right now, I think. Unless I'm forgetting a game? I think I first encountered NPCs following a daily routine in a big 3D world back in Outcast, and ever since then whenever a game comes out which doesn't have the feature, it's been a bit of a disappointment.
Of course there are some games where the story doesn't warrant putting in that much work for the feature. For example, in NWN2, it would be pretty pointless to add that feature. Just the way the game is structured, and the way the story plays out, NPCs who had a daily routine would add almost nothing to the game.
