Quake 3 in Mplayer...56k modem.Boy,,I sure miss that speed.........
Medal of Honor - Allied Assault, around 2004/2005... just randomly joined some server, played a few maps, and ended up sticking with it for quite a bit of time.
Too bad I never tried Quake until I accidentally bumped into QL 1 year ago. :/
Don't make me angry, The voices in my head don't like it when you make me angry.
quake2 1997 on a server called ifco cry havoc - cry havoc was a class based mod. I was using keyboard at the time - a regular on the server took me under his wing and showed me the way of the mouse, and my mind blew. He then showed me rocket arena 2 and my mind exploded.
1on1 rocket arena 2 was very cool because the spectators hung out in stands that were ACTUALLY part of the map. So it really felt like being in a gladitorial arena.
quake2 demo, 98. After getting to full in 1999-2000 the mod I remember the most is ra2, and most nostalgic (since there's nothing like it) is q2 ctf, particularly the l-fire variation with offhand hook and airacceleration (qw-like), and probably most importantly the fact q2ctf maps were all made with grapple in mind and that's long forgotten (big, movement and teamplay possibilities, etc.).
Quake 3 in 2001 in LAN with friends. A year later Quake 3 OSP for few weeks and then switch to Ra3. In 2001-2003 i've played some Q2 in LAN and ActionQuake (2) in LAN as well. Never played other games.
COD 4 and Left 4 Dead. Man, those were the times.
The first FPS I played online was BattleField 1942's demo. The first FPS I played online a lot was WarRock. Then I discovered Quake Live in 2010.
First FPS i started for real was a piece of cr*p game named Warrock, actually made it far, our guild was ranked 1# in the world lol.
