I've started up a new guild.
The guild is more aimed at showing there is a base of PSO2 players who Would like to see Linux Support, and or continued Win7 support. But is also open for more regular players.
With Kernel 5.11 coming this year PSO2 may start working with Proton https://www.gamingonlinux.com/2020/10/collabora-expect-their-linux-kernel-work-for-windows-game-emulation-in-kernel-5-11.
Add in that Denuvo has worked with Valve to get it's DRM+Anti-cheat into Steamworks. https://www.gamingonlinux.com/2021/01/steamworks-gets-denuvo-anti-cheat-heres-what-irdeto-say-about-linux-support
