You also may play Rise of the Triad or Hexen/Heretic if you like that. Dark Forces (original one) is also pretty good classic 3d shooter. Or go slightly deeper in past and try Blake Stone or other wolf3d games. Strife is worth to try because it is somewhat unique rpg-like game for doom engine, although it is very long. There were also some now-forgotten games like Cybermage or Cyclones. And much more.

And this for being true oldschool 3d connoisseur: https://www.mobygames.com/game/dos/dungeons-of-kremlin (joke, don't even try, this game doesn't worth it)
