Xbox Game Pass is a monthly subscription service that gives you immediate access to over 100 games for $10 a month. You can even bundle Xbox Game Pass for Xbox One, Xbox Game Pass for PC, and Xbox Live Gold together with Xbox Game Pass Ultimate for $15 a month. According to a recent interview with Xbox's Phil Spencer, the subscription service as "millions of subscribers" and it seems like it's growing.

While Xbox Game Pass saves gamers a lot of money, it's beneficial to developers as well. According to a report by GamesIndustry , the service is seen as more of a promotional tool by third-party studios. For example, if you take a look at Descenders, it has been played by 600,000 gamers. Creator Mike Rose credits part of that success to Xbox Game Pass.

Rose said the following to GamesIndustry in a recent interview.

Sounded like b*******, right? Weirdly, it's true. It surprised me. Being on Xbox Game Pass means that you basically have constant featuring on Xbox. Your game is on the dashboard all the time... People are seeing our game every day. And because of that, during launch month, our Xbox sales — we didn't do any discounts on it or anything — quadrupled, and have now settled to about three times as much as before. It's essentially an advert; a straight-up advert. And now Xbox is asking, 'Oh, can we feature Descenders in more of the Xbox Game Pass advertising?' Yes, you can. Of course you f****** can.

While Microsoft has said that Xbox Game Pass boosts sales in the past, it's more concrete when a developer says it. The fact that it quadrupled how many copies Descenders sold is quite a feat. Hopefully, this success will continue into the future even as more titles are added to the service.
