Lmao "if the developer wants to".
Perfect way to shift the blame away from MS when they start pushing incentives and obstacles that make devs not want to support the vanilla Xbox One.
It's not much different from their loopholes in the wording for their parity clause contracts that allows them to pressure devs to support the platform or risk not being able to develop for the platform at all. Sure, you they have the "choice" to develop for any platform they want, you just don't have MS's support if you don't play by their rules.
What? It's the dev choice of course, but they aren't going to ignore a system with 30M sales. What's wrong with you people?
