Think of it this way. What do most games get you in the end? Nothing but the satisfaction that you beat it, right. Older games in the Arcade ranked you according to how well you did. You would be judged beside your fellow game players.

It is like Achievements within it's self has become a game. Pokemon even. You gotta catch them all, or in this instance, gotta PLAY them all.
