13 games for one L4D2!

Hello, everyone. :) I am new here, and I have one offer!
I will give keys for:
ArmA 2
Tom Clancy's Rainbow Six Vegas
Tribes Vengeance
Nexus The Jupiter Incident
MX vs ATV
Grount Control 2
GT Legends
World of Tanks
Ghost Recon Advanced Warfighter
Escape From Paradise City
Kane & Lynch: Dead Man (I heard it works with some Rockstar games like RE5 and GTA4, I swear lol)
Empire Earth
Brothers In Arms Road to Hill 30
Dark Messiah Might and Magic MP (only this game works with steam)
I want:
One copy of Left For Dead 2

I don't need those keys, and I really want L4D2. :)

P.S. I made a mistake, 14 games :)

Bump.

I might be interested

Added you on Skype. :)

Why don´t you sell those Keys for real Money? So you can get L4D2 and you´ll have Money for sth. else ;).

I don't have credit card, and I got bunch of those keys for free. It can be really complicated, and this way I can just give keys and get L4D2 really simple + I got keys for myself. :)
