Man IHMO is too overpriced, you can buy new at many cdkey store ad 14,99$ and on Amazon.com the W3:Battle Chest cost $19.99, the retail copy, so not only the key, with the free shipping...
Anyway, if you want to trade, i have unused games like GTA4, STALKER, Street Fighter IV, Tom Clancy Adwanced Warfighter 2 and some other i don't remember atm
If you want to trade send me a PM and we see on skype for all the detail
EDIT: I don't know why, but i think i know you, your name is M_ _ _I? If not, sorry and forget it.
