I usually pick up new released games on Goozex within 2-3 months after release. Demon Souls, Uncharted 2, Mass EFfect 2, God of War III, Ratchet and Clank: ACIT, all of the new Call of Duty games, New Super Mario Bros Wii, Metroid Prime Trilogy, Wii Sports Resort (Plus Motion Plus accessory), Fallout 3 GOTY... and more I just can't think of them all.
As of now I am about to get matched for Red Dead Redemption and eventually Alan Wake. But I don't even need those games because my backlog is so damn huge!
If you learn to juggle new releases, you can pick up all of the latest and greatest for around $25 each. I never had a problem waiting because I always had a backlog of new games. See how it works?
If you are trying to get the rare games, you are going to have to wait a much longer time as there is little supply to high demand.
Thanks OP, in for 2000 points for now, may bite for even more points.
