Wow, I didn't realize that Stadia games are running on Debian and Vulcan. https://stadia.dev/about/ That is a hard sell that you have to (likely) port your game to a completely different OS and graphics API for a presumably small customer base.

There's a large number of games that use premade engines (eg. Unity, Unreal). As long as the engine supports Linux and Vulkan (I believe both Unity and Unreal do), there's no real issue in supporting that platform.
