Skyrim XB1 - Unopened. I pre-ordered this and then sometime after the release date it still hadn't shipped, so I picked up a copy in store...and when I got home the pre-order shipped. I don't really return things so...factory sealed Skyrim.
South Park: The Fractured But Whole XB1 - Unopened. Stick of Truth offer expired in 2018. Unwanted recipient of a number of games, never opened them.
Wolfenstein: The New Order XB1 - Unopened. Same as above.
Wolfenstein II: The New Colossus - Same as above.
Tom Clancy's Rainbow Six Vegas 2 XB360 - yeah, guess what. Pre-owned before me I think, never played it, not too interested.
