i only buy like 4-5 games a year(unless i get cheap old new games) rest of the games i want to play i rent from gamefly so i have no need to buy used games.
Your prior posts crusading against buying used games (from Gamestop) and instead buying them new so you can "support developers and publishers is full of hypocrisy...
1. You admit buying new games, opening them, playing them and then returning them - a practice largely not permitted at retailers.
2. You rent certain games rather than buying them.
3. You do buy used games (from Amazon), just not from Gamestop
4. You have no problem waiting for games to fall in price rather than pay full price on release (which I don't take issue with since we are all CAGs, but I merely point it out since you are the one arguing that the devs and pubs are losing revenue when people buy a used game for $50 instead of a new game for $60; it's the same scenario, people wanting to save money and pay less whether its used right away or marked down months later.)
By your own logic, you are no better than the people you've been railing against for buying used games at Gamestop because used sales don't support the developers and publishers. It sounds to me that you simply don't like Gamestop, and that is all fine, but don't use that to make some argument in support of Microsoft's DRM on the XBone.
