I want it to be an exclusive Xbox One game (No CoD: Ghosts), and I'm kinda torn between Killer Instinct and DR3. I only have money for one game, what should it be?
Killer Instinct is rumored to be one of those micro-transaction games as well - which may simplify your decision. It might end up being free or very low cost, with you paying to unlock and use only the characters you want.
Dead Rising 3 looks pretty bland - at least compared to the previous two titles in the series.
Destiny seems interesting if you're a Halo fan. Or, you know, Halo.
Anyway, why not CoD? An Xbox without a copy of CoD just seems... wrong. Don't forget you Doritos and Gamer Fuel.
