Recently I fired up an old copy of Elder Scrolls 3: Morrowind using the OpenMW client, and it’s really breathed life into that game for me. It’s always been a favorite but the original engine was really showing its age. I’ve since been playing around with other OSS clients like Quakespasm, ZDoom, and recently discovered Arx Libertatis. I’m curious - what other commercial games are there out there with open-source Linux clients?
For the sake of this discussion I’m talking about community-created projects and not Good Old Games ports (although those are awesome too).
