Installed this on Linux Mint 22 via Lutris and appears to be fully functional and stable (a few hours in it). As for the game itself, they did a great job on this update. I don't notice any changes to the original mechanics. They just added a useful auto-mapper and nice graphical updates. Wish everyone did "classic updates" as competently as this.
Had problems running the Linux version, but the Windows version runs perfectly through Lutris. Just install the Windows version through Lutris... and use the Lutris "run EXE through Wine prefix" command (the 2nd "up arrow" button next to the "play" button)... it will install version 2.5 and you can install patches and mods through that. Runs perfectly through that. Aside from that, it's good old BG2 (version 2.6 with some additions). I added some large "tweak pack" and everything runs without any issues.
