Paradox doesn’t really bother.
Even the games that have native Linux ports regularly have massive issues. Currently you can’t play CK3 multiplayer since it immediately goes out of sync, works fine with proton though. The Linux version also crashes much more.
Similar story with Stellaris, where every other update the clients become completely incompatible.
The idea of a “Prison Architect” series of games is just conceptually wild to me. I wonder if in a hundred years this will have the same ring to it that a game like “Slave Plantation Architect” would have today. Just remarkably crass and tasteless.
With proton there’s no need to Wine about it
Native Linux support was often problematic because too many developers would use a third party to port the game and then fail to maintain it.
I absolutely love the Steam Deck and I’ll easily take the trade offs that Proton gives us. Maybe one day Linux will gain enough market share to justify more first party native support.
PDX games have always worked for me with Proton. That should be fine.
