Hi, GSB+GTB can be bought for 1 dollar right now, so I don't know if anyone will give you Assassin's Creed 3 for them, but I am interested in Tank Battles and I can offer you games from different bundles for it:
Aquaria
Cogs
Crayon Physics Deluxe
Defense Grid: The Awakening
Dungeons: The Dark Lord
Eschalon: Book II
Geneforge Saga
Metro 2033
Nightsky
Splice
Superbrothers: Sword & Sworcery EP
The Binding of Isaac + Wrath of the Lamb DLC
Waking Mars
If you are interested in any of them we can trade. If not then I wish you good luck with other offers.
Hi. I'm offering GSB and/or trading cards. If you're not interested in those items, I have PayPal for Assassin's Creed 3.
Might be interested in buying other games. Feel free to ask. Thanks! :-)
I am not interested in Dota 2/TF2 keys.
