I still use it but will probably be cancelling soon, since Fallout and Black Ops will be taking up my time. Their library is good, but I couldn't get new releases right away, they were always out for the first little bit, but that could be bad luck. Delivery times are also a bitch. From the time you send games away to the time you receive new ones is almost two weeks. Although this can be avoided if you keep one game while you send the other away, but if you don't like them both than you're sol. I called them to cancel it for that reason, but they said it shouldn't take that long for such a short distance and gave me a free month and promised speedier delivery. We'll see how long that lasts though.
I'd give it 6/10.
Pros - Tons of games to choose from, keep them as long as you want, cheaper thenBlockbuster, no long term commitment, good customer service.
Cons - Long waits between game delivery, had to wait a month or so for new releases to finally be in stock.
