Giving GameFly A Shot

My roommate from last summer has offered me a free month subscription to the service. I am currently waiting for Harvey Birdman : Attorney At Law (Wii) and Armored Core 4 (XBox 360), which should be here in the next few days. GameFly seems like a decent way to get games that look fun enough to play, but not pay $60.00 to actually own the copy.
