I am including The Walking Dead only because I am not 100% sure I will add it to my library, as I own it on Xbox Live already. Have a look at my wishlist as a starter, but I admit is isn't complete. You can add me on Steam. I'm open to keys if I will add the game to my library. I am open to wallet as well, for the right deal. Even if you have only a smaller offer, leave it here, mail me or chat with me on Steam.
Thanks for reading!
