I have finally decided that I want to get an Xbox 360... I have an Xbox Classic (perfect working condition) with one black second generation controller and several wireless ones. I also have the following games:

Halo: Combat Evolved
Halo 2 Limited Collector's Edition
Star Wars: Battlefront 2
Star Wars: Battlefront
Star Wars: Republic Commando
Burnout: Revenge
Project Gotham Racing
Project Gotham Racing 2
The Elder Scrolls III: Morrowind
Spiderman 2
Cel Damage
Mechassault 2: Lone Wolf Limited Edition

Now my real question is, will my local Gamestop allow me to trade in my Xbox system along with my collection of games for store credit... and if anyone has any experience, how much could I possibly get, realistically?
Thanks guys... Now, assuming I decide to sell it to a friend, how much should I charge, once again, realistically .

Realistically, you'd be better off to try and sell it to someone you know. I have traded in games and systems several times and I am always disappointed in the outcome.
