I think Minecraft is a great example of this. There is such a wide variety of ways to derive intrinsic or extrinsic rewards from the game that it encourages a wide variety of play styles tuned to each player's psychology. Watch my oldest daughter play, and you'd think Minecraft was purely an RPG about slaying as many bag guys as possible. Watch my youngest, and you'd think it was an adorable farm animal simulation. Watch me, and you'd think it was a low-res architectural sandbox.
