Honest question, what do you consider not compatible? I switched to Linux earlier this year and 100%'d Armored Core 6 (Verrrrry good game everyone should play it) and I’m currently playing through Cyberpunk 2077 + Baldur’s Gate 3 co-op with friends. If AAA games like these work pretty well I’d assume the vast majority of those 60k games work as well.

I haven’t played FFXIV since switching to Linux so I haven’t tested this, but it seems there’s a Dalamud plugin to have the ACT plugin working without having to deal with ACT itself. https://github.com/marzent/IINACT

It was around 22€ if I remember correctly

I honestly had to do a double take when I went past this, didn’t know people were out there eating gamepads
