Joining the long-growing list of incentives to join the OnLive Service is Arkham City. Pre-Order the game for the service and you can get a free system or a free game, which is pretty awesome. This deal is only good until 09/14/11 so better get on it while the deal is hot! Keep up the good work OnLive. I don’t have the system because I’m poor but I certainly appreciate how you’re treating your customers.
