The diversity of Linux distributions is one of its strengths, but it can also be challenging for app and game development. Where do we need more standards? For example, package management, graphics APIs, or other aspects of the ecosystem? Would such increased standards encourage broader adoption of the Linux ecosystem by developers?
That already happened though. Tens of thousands of games on Steam can be played by hitting the install and then the play button. Only a few “competitive multiplayer” holdouts with rootkits and an irrational hatred of Linux don’t work.
