The 1993 videogame Doom practically invented the First Person Shooter, although that really started with its predecessor Wolfenstein 3D.
It is still my favorite videogame. I had the privilege of contributing to the Super Nintendo version of Doom. My name is in the credits. However, the Super Nintendo version is not as good as the PC version. (See the video at 32:45.)
I haven't played many newer First Person Shooters, which means that I'm at least a couple of decades out of date.
So I find myself wondering how you can best a perfect game like Doom? All First Person Shooters have their roots in Doom. Newer games have better graphics and more story.
