Xbox head Phil Spencer says Microsoft is obligated to support Xbox 360, meaning the company does not plan to cultivate games exclusively for Xbox One in the near future.
Spencer explained why the company isn't dropping all of its efforts elsewhere to focus on boosting Xbox One's first-party lineup of games in an E3 interview with Metro.
"If you bought your Xbox 360 a year and a half ago, I think we have an obligation there," Spencer said. "We're going to sell millions more Xbox 360s before this generation is done and when people make a £100+ commitment to us, they're gonna come in and buy an Xbox 360, I want to make sure that there's content for them."
Investing in the new generation is important, Spencer said, but not everyone has bought an Xbox One yet and Microsoft knows abandoning those consumers would be a poor move.
It's part of a delicate balance, because a strong first-party line-up is a good way to encourage third-party developers to compete on the system. But creating a good feedback loop isn't the only thing on publishers' minds.
"For a third party this is the nice part of the curve for the last generation, because you've got millions of people out there and they want to sell content that these people will buy," Spencer said. "They also want to kickstart the new generation successfully, so you'll see a lot of them doing a little bit of both."
