Oh yeah, also -- video games are definitely in their infancy as an art form. Hell, I think musicals are still in the cradle and they've been around for the better part of a century. (Musicals: People inherently expect less from them, for starters! The best musicals often make hysterically melodramatic B-Films. The best one, I think, is Avenue Q, which embraces the conceit and uses the genre to the fullest.) I wouldn't expect any high art from video games for a long time -- just clever forays.

Incidentally, Dragon Age: Origins is a damn good foray and you should play it. (And then leave Awakening and 2 alone, as they are deeply flawed. Well, maybe play DA2 because the gameplay's fun, but other than that.)
