Baldur’s Gate 1 & 2…the exploration of the wilds while so vulnerable in the first game is something I’ll never get bored of while the second game just takes it to a whole other level with your power growing so immense. They still totally hold up with the extended editions!
I run it through Steam as a “non-Steam” game via Proton and have also run it with Lutris. It runs on both 100% fine, if not even better than Windows. In fact, this game running great has convinced me to finally drop my dual boot!
