Excellent article. I agree that Assassin's Creed deserves a mention (although it goes downhill from the revelation on). How about Disgaea? Though the issue is never overtly dealt with, it's HEAVILY implied that both of Laharl's parents kill themselves, and then end up helping him in mysterious ways. Among other things. I'd also support getting a Fallout up there. Myst? Portal? Both highly thought-provoking games.
