Little Red Dog Games developer of Precipice, Deep Sixed and Rogue State Revolution spoke in an interview with Linux hardware vendor System76 about developing games on and for Linux. It's quite an interesting interview that goes over details about how they make their games, their use of Godot Engine and why they think it's a good idea to develop for Linux.
Starting off as hobby developers making point and click adventures, Little Red Dog Games are now a full-time studio with multiple games out on various stores. Their lead programmer, Denis Comtesse, is a Linux user and so using the likes of Godot makes it all relatively easy for them since it has great cross-platform support.
They're not exclusively Linux developers though, since they support multiple platforms and so they do need to work with other systems too and it sounds like Godot's multi-platform support is in real good shape there too, with LRDG CEO Ryan Hewer stating how "I would say it’s less than a half-hour’s work to be able to support Linux consumers out there" and that "Linux users represent about 7 percent of our market right now as game developers, which is more than enough to justify the minimal steps needed to be able to make the game compatible for Linux PCs".
Seeing 7% might be quite surprising, since according to the Steam Hardware Survey which we track on a dedicated page, Linux hovers around the 1% mark but we've seen lots of other developers show higher than that too in previous articles.
Later in the interview Hewer mentions on the subject of supporting Linux that there's "no reason not to. It would be a huge oversight for any developer to not be putting out packages for that 7 percent demographic, and it’s painless within Godot to do that.".
