Check out Wrath of Ruin, game based on q1 engine (darkplaces) in a dark fantasy setting (like witcher), its much better than its trailers, and imho. has much better aesthetics and gameplay than q1 while still maintaining the q1/doom gameplay feel, it is what q1 s hould have been imho. :-)

Also for q1 players, checkout XMAS Jam 2019, single player map pack by talented mappers, really going creative with what its possible with Q1 gameplay, should played with quakespasm engine
