Hmmm… Must have been the strange Doom-like game my older brother fished out of a cereal box many years ago. Featured a cereal guy fighting walking globs of goo with a spork. An imaginary dollar to anyone who guesses the name.
Half-Life in 1998, mainly playing Deathmatch 
Duke Nukem 3D. Shareware, i was 5 i guess.
Chexquest. lol I did the same game long time ago.
quake or doom. I cant be 100% either way. Back when I played it I was more of a platformer kinda of gamer so I didn’t spend too much time on it.
EDIT: Or could it have been goldeneye. IDK any more
The doom demo.
Half Life 1 In 1999.
GoldenEye of course.
Why would it?
we are talking about the first fps you ever played, not your first sandbox and/or RTS
C&C Renegade is a FPS.
Some James Bond game on my gamecube.
Goldeneye: Rouge Agent?
Same here
I also played some Doom or Quake or whatever on my Snes after that.
But the first FPS I found awesome to play was a demo of HL1. It was the first FPS where I had to use the mouse, so I thought it was great.
Duke Nukem 3D, I’ve been waiting for that sequel ever since…
Goldeneye 007.
The simple joys of shooting people made out of cardboard boxes, screwdrivers and doorstops.
What makes it a sandbox game? It was ridicolously linear.
He was referring to GTA1.
Why did you think it was an FPS?
No it wasn’t Goldeneye, I know that for a fact, thought I know it was around 2002 or something like that. Also (It was mainly 3rd person as well, but you could change it to 1st. Another thing was that you were Brosnan’s Bond.)
Half-Life 2 about 3 years ago. Since then I’ve hardly played any games that aren’t FPS.
