O.K., I'll admit, I'm starting to cheat with 2 games instead of one on the list, But it's hard to choose one game, especially if it's part of a franchise. With Dead Rising 3 an Xbox One exclusive, Dead Rising 4 coming later this year for Xbox One, and the series 10th anniversary coming up, it makes perfect sense to put both Dead Rising 1 and 2 on Xbox One.
Dead Rising was one of the first open world games on 7th generation of consoles and is still a fun, zombie slaying good time. Dead Rising 2 improved the game with it's weapon combination system and some great DLC storylines. Hell, Dead Rising 2 was even remade with Frank West as the main character, as Dead Rising 2: Off the Record. So come on Capcom and Microsoft, give us more Dead Rising on Xbox.
