Um, Minecraft was executed very well. Maybe not as technically advanced as it could be, but Notch had a very good grasp on the player loop (you explore, you get resources, you build something..) and his artistic choices had a certain "poetry" (take now iconic creeper as a canonical example), which I think greatly contributed to the success of the game.
