  • vkQuake

    Discontinued Vulkan Quake port based on QuakeSpasm

  • That last one is an open source engine for a trio of existing free games, but if we count open source engines for commercial games the amount of famous examples grows exponentially. All id Software games up to Doom 3 have had their engines made open source and have a huge number of modern versions available for all of them. So Arcane Dimensions, the greatest by a mile Quake campaign ever made, was completed just three years ago and you need a modern open source engine like vkQuake to play it - even the Quake Remastered engine can't handle the huge AD maps. There's also an open source Morrowind engine, an open source Freespace 1/2 engine (Diaspora above actually runs on this), an open source point and click engine called ScummVM that runs so many old adventure games it's almost an emulator...
