Warhammer 40,000: Space Marine
Aliens: Colonial Marines (I have all DLC so we can Bug Hunt)

Also interested in modding games like Aliens: Colonial Marines, Aliens Versus Predator, Fallout 1/2/3/New Vegas/4, The Elder Scrolls: Oblivion/Skyrim/Morrowind when I get it

And I have a backlog of horror games to purchase in my wishlist.
