I signed up for Gamefly

Had it for 3 years now, can't beat it.

2 games out plan, rent games like AC3/FC3 beat and send back.

Love it, fast shipping too, takes me 2 days to get them after they ship, 2-3 days to return and get a new one coming.

I can see it being something I would use off and on every few months. My brother had it for a time and ended up canceling because it was hard to get new titles and there weren't that many titles that he wanted to play. IIRC he liked it for getting a good handle on games like bayonetta, but there were far more games that he had absolutely no interest in or time for playing.

I'm currently using Gamefly myself. I'm being smart about it though. When there aren't too many great games out at once, I'll offer a friend of mine to use up my second game and charge him half the price of the game. (CoD BLOPS2)I have my copy and he has my other one. He gave me $30 to play it and our agreement is that in 3 months I can choose to return it or let him borrow it another month at $5 for the month. 2 game plan is the way to go IMO
