I’ve been getting really into Vampire: The Masquerade - Bloodlines and Redemption, old school Runescape, Ragnarok Online, Arcanum, Diablo II, and others lately, and I’m looking for more 90s/early 00s PC games that will run on my new Thinkpad E15 G4 running Arch Linux.
Dungeon Siege (2002) is a nice RPG; 3D, isometric-style default camera, slightly tactical order-based movement/attack, and a fully streamed world - so no loading screens during gameplay.
It certainly has its fair share of jank as well, but it does well otherwise.
