Having just finished playthroughs of Prey, Dishonored, and Dishonored 2, I decided I had to play Arkane's first game, Arx Fatalis. $1.64 later, I had a copy from GOG.
Interestingly, Arkane made the source code for the game open years ago. This has led to the development of Arx Libertatis, which is an open source port that runs nicely on Linux. Easy to set up, and runs great on modern hardware at modern resolutions.
