In no particular order:
Unreal Tournament (PC) - my first foray into online gaming (though I don't do much of it these days), and though if you look at it today and say the later versions are far superior, it just was all around fun. I tried getting back into the UT frenzy with UTIII on PS3, but the franchise is just too fast paced for me these days.
Halo (Xbox) - out of the three, easily the best of the bunch. The other two traded single player quality for multiplayer, while this one had both an enjoyable SP experience as well as some of the best multiplayer of its time. An overall great experience. It's unfortunate this level of quality may never be seen in a Halo FPS again.
Zero Tolerance (Genesis) - what got me into first person games. Me and my brother would play this game for days and just see how far we could get. You could backtrack to any completed level to find any extra ammo and/or health you may need. A wide variety of enemies and some excellent boss fights.
Rainbow Six 3 (Xbox) - one of the first Xbox Live titles I owned (alongside the fantastic Crimson Skies), and really was the title to play on Xbox Live for me until Ghost Recon 2. This was before Halo 2 hit, this was when Xbox Live had a somewhat mature crowd, where you can enter into a room of randoms and not having to worry about muting the other 10-15 players. Late night sessions online playing terrorist hunt and team games was what made this game so fun. Tried reliving the fun with R6V on 360 but the online crowd these days is total garbage. Friends only it seems.
Red Faction 2 (PS2) - it may not be the most distinguished series out there, but this game had some of the best multiplayer to boot. Whether it was with human friends or bots, I would play day long sessions just trying to outlast the competition. The single player portion lacked a quality story but was enjoyable to play every now and then to get away from the MP addiction. It's unfortunate THQ has completely ruined all hopes for this franchise to return to its origins with Red Faction Guerrilla.
Notables:
- Call of Duty 4 (360/PS3) - had everything going for it. An intense single player campaign, a large scale multiplayer system, and just some fantastic gameplay. Unfortunately it was too short for its own good. This day in age when someone shells out $60 for a game, they should expect at least a 12 hour campaign. This game is beatable in less than 7 hours.
- Medal of Honor (PS1) - what started it all for the MoH series. One of the three quality console games in the franchise (other two: Airborne and Frontline), and for its time it was one of the better shooting experiences on the PS. I hope for a PSN release.
- The Orange Box (360/PS3) - I was never big on Half Life. I wanted to be. It by all means bled high quality, and Valve has done a magnificent job raising the stakes for themselves time and time again. But the story just wasn't my kind of thing. However The Orange Box was probably the best $60 I ever spent on a 360/PS3 game. Now with it being
