Thing is, CRPG still stays CRPG. In some remote future maybe we will get some powerful AI DMs, who can on-fly morph any pre-set story, based on parameters we've set. Basically playing REAL D&D, but with good graphics and fully voiced.
But right now CRPGs still limited to what actually is coded. And Tav in practicality is just little no-one, somehow get caught in whole story. No real backstory, as game never will tell you anything about it (rest of race and class election). And no personal quests.
