I really liked Dragon Age: Origins. It is one of the most in-depth RPG's I've played. Ultimate Edition gives you a sociopathic Baraka (A Golem), adds a good backtracking quest (You have a reason, the story is further developed, etc), adds a quest fleshing out the Grey Wardens, and includes multiple after-and-before the events in the game (Awakening being a big one - you experience the events that led to one of your characters being there, the effects of your actions, the conclusion of a romance, etc).

As a side note: if you do purchase DA: O Ult. Ed. and want better skin models (or to play as a Woodelf/Dalish mage, there are mods on Nexus for that)

It was like Neverwinter Nights 2, only more realistic/detailed...if it had a toolset to create new worlds/characters, it would be my favorite game. As it is, it comes in as my second favorite.
