depends on your platform, but cross platform happy games I had a great time with Doom 64 (by the same guys as the quake 2 remaster here) and Project Warlock; which has an art style that takes a minute to get over. but it’s got great level design and a really great power creep. had a lot of fun
on pc there’s a lot more, there’s the remasters like Blood, Shadow Warrior, you can get Duke 3D going with EDuke (or buy the fucked sound quality version on steam…), for modern there’s Nightmare Reaper that brings in a rougelike quality, Dusk which is the best Quake engine game ever not made on the Quake engine, Amid Evil, Headon, Project Warlock 2
