Titles from Microsoft's indie-focused ID@Xbox programme have brought in a whopping $1bn.
That's according to the scheme's chief Chris Charla, who revealed this in a blog post over on Xbox Wire.
That $1bn figure is roughly double the platform holder's previous milestone, which Xbox made at Gamescom 2017. Just seven months ago, the firm revealed that more than $500m had been generated.
"It's been a fantastic year," ID@Xbox's European chief Agostino Simonetta told PCGamesInsider.biz.
"At Gamescom 2017, we announced that ID@Xbox had generated over $500m and we had 600 games. Now, since the start of the scheme, ID@Xbox has generated over $1bn. We've effectively doubled the amount of money these games have generated in just six months. That's great for Microsoft, it's great for the developers.
"Now we have 2,800 developers with dev kits and almost 800 titles have launched across Xbox and Window 10 from 477 developers across the globe. I think we probably have all the continents covered. Since the launch of ID@Xbox, more than 4bn hours have been spent playing our games, which is about 450,000 years. We obviously know the data, we know how much we have sold.
"But when you take a snapshot like that and look at the data altogether. It feels good. It feels like we're going in the right direction. At the same time, the feedback we are getting from the developers is positive. We put a lot of effort into making sure they have the best possible experience, and invest a lot in making sure we promote them as much as we can."
Pressed as to why the amount of money made by ID@Xbox games, Simonetta said it's a combination of its ecosystem as well as some particularly successful titles.
"You always have titles that are extremely successful; you have the outliers. In general, a lot of titles are just generating more money. We have very successful titles coming through. You have the big ones, you have outliers. They are unique. But in general we feel really good about the ecosystem. It's a combination of the entire ecosystem growing and some outliers that really help that."
