The first FPS (First Person Shooter) you played?

GoldenEye 007 on the N64 most likely. I was born in 1991 and it's the earliest FPS I can remember playing with my older sister and brother.

 

Doom on my then shiny new Dell Dimension P75. Damn, that thing was fast (at the time). I even overclocked it moving the MB bus jumper from 50 to 60 MHz, running it at 90Mhz. 8MB of RAM. 14.4 modem. Number9 video card with 4MB on the card. So sweet.

 

OG Doom 1993.
