Enemy Territory Quake Wars for Quake.

And Quake Champions as well but given its online only nature with no bots, LAN or private servers, it’s impossible to be DRM free right now. Quake Wars has offline play and bots though, so that’s always playable offline.

Thank you! And as you said, I won't be adding Quake Champions since it is an online-only title.

Enemy Territory Quake Wars

The fact that Quake Champions doesn't have those features does irk me greatly, though. Despite the controversial addition of passive and active abilities, I do actually find Quake Champions quite fun, at least as a different experience. But I won't be able to play that years from now thanks to its online only nature, unlike Quake 3 Arena or even Enemy Territory Quake Wars which I can play anytime I want forever.
