I can offer the witcher 3, gog version. I want wolfenstein new order 14.99, nidhogg 1.49, tabletop simulator 13.99, and duck game 10. In total all the games I want for witcher 3 are 40.47. You end up saving about ten bucks from this trade. To be clear, I will trade witcher 3 for the aforementioned games.
I have an extra key for witcher 3 as a result of buying a graphics card.
What you give me for it is up for discussion, though I badly want duck game...
