In that case we will discuss if there is a market in Linux for games.
Do you believe launching games on Linux will substantially increase their game sales? Not sure about that because Linux is most used by non-gamers and the real market is corporate servers.
People here already says Somy doing Windows PC ports is a waste of time and money… imagine Linux PC ports.
In another side I agree with you the use of Proton is not support Linux at all… Valve focusing in Proton to Steam Deck basically killed any chance of Linux being a viable option as game platform.
Even devs that for hobby did Linux version of their games in the past won’t do anymore…
