Modern Warfare is educational too (modern history, tactics, orientation)! And PacMan (culture). And Dalkstalkers (art). I can continue forever.
Maybe the Mario series is not educational, but that is the only title I can think of which isn't. That's a game with moralistic Bible Belt crap (hey rescue the holey housewife!, she's a ---smurfette--- you know?).
Mario is the Nintendo equivalent of Ronald MacDonald. Make the kids greedy and spend tons of money on their demands.
