I'm wondering if it would be considered off-topic to discuss "Doom Clone" FPS games from the 90's in this thread?
Wolfenstein 3D was the predecessor to Doom, and you had things like Heretic, Hexen, Strife, and Chex Quest directly based on the engine of the classic Doom games.
While the Build engine games like Duke Nukem, Blood, and Shadow Warrior aren't built on the same engine as Doom, they're typically considered part of the "Doom Clone" family given the similar mechanics and the era that they came out in.
Heck, there were a lot of Doom clones that I played on the PS1 that aren't even talked about anymore like Alien Trilogy (basically Aliens TC but officially licensed and including stuff from Alien 3 and the first Alien) or the Star Wars FPS game where you played as Kyle Katarn (forgot the name of the game itself)
IIRC, there was even a South Park game like this for the PS1 in the late 90's but it was pretty terrible, which was the main reason why Trey and Matt took a more active role in making Stick of Truth and The Fractured But Whole
