I've never played any Baldurs Gate, but am interested in playing the upcoming one. Checking proton db, it looks like the previous games had good Linux support (even native support?).
What are the odds we'll see Linux compatibility with this newest one?
Larian's previous game (Divinity Original Sin 2) didn't have a native port, the one before that did. I think it's unlikely that BG 3 will get a native port but it seems to work well enough through Proton.
Which previous games were you looking at by the way, BG1 and BG2? BG3 has little to do with those except for the setting, it's a really different game (some dislike it for that).
