In last year’s survey, 66% of developers reported working on games for PC, while this year’s number is significantly higher at 80%. In comparison, 38% of developers said they were working to put their game on PlayStation while 34% said they were developing for Xbox.
Now, GDC clarifies that “Steam Deck” was not specifically listed as a platform option in the survey. However, when answering which platforms they were developing for, 44% of respondents who chose “Other” did mention “the Steam Deck as a platform they’re interested in,” which potentially shows a significant focus on Valve’s handheld.
How many of them are indie developers and how many do AAA? (Edit: The article says “Something to remember here is that the majority of devs are indie developers rather than larger AAA studios.”) I think one of the biggest contributors to this is that supporting Steam Deck is much easier thanks to Proton, especially if they already have a Windows version. And the extra exposure they get through the Steam store and various articles and forums by having a Steam Deck version.
