Doom isn’t 3d, it’s raycasted 2.5d. It’s a completely separate type of rendering that has nothing in common with real 3d.

Most people would call DOOM a 3D game. Its popularity spelt the end of 2D games which is why people bring it up.

It doesn't matter that it's raycast with billboard sprites, it was first-person-perspective with pixel-perfect lit texture-mapped wall and floor rendering with lifts and stairs. 3D enough.

Quake released the day before Super Mario 64.

Those 48 hours were likely the peak of video gaming. Certainly they have yet to be equaled.

As a Marathon fanatic, it killed me that the game didn’t get more love. I recall watching a Doom game and someone shot a rocket at a player above them. The path of the rocket was bizarre and being baffled that this was ‘good’.

It was a fun era to live through as the progress was so quick.

Hey, Mario 64 isn't "real 3d". It is just a projection of 3d coordinates to 2d triangles on a 2d screen.
