I wouldn't recommend the keep option. If you are already using the service, there are no return times, so you can keep until you beat it and get it again at another time. Besides, it also means your paying full price for a used game, a vastly used game at that. As for the service itself, I really enjoy it. While some of the just released games might take a little bit to get to you, games that have been around for a few weeks are usually easy to get. The service is great for the price they want, though I recommend the 2 game package, seeing as how it leaves you the ability to play one game while the other is being shipped.
