The game interface allows for the community and the politics to be completely community run, too. Giving the players the framework for how actions are executed in a game and letting them work out the rules for when and where actions are taken, and against whom, and for what reasons. It's like a more complex version of Risk, which can be done on a board or on a pencil. Games where the user's imagination can be adequately expressed without having to code in tons of actions, and where the communication matters too, will always have their place. Look at tabletop Dungeons and Dragons - mostly imagination. Still popular anyway.
It probably just comes down to the fact that we're all dorks in some way or another.
