There were two competitive multiplayer games that I really enjoyed:
1) Jedi Knight II: Jedi Outcast - that was while ago, almost 10 years I'd say... I loved saber dueling, and actually got pretty good at it; I remember one of the more popular maps had a "pad", a circular platform that was usually used for duels, and one night I was on such a streak, I got the nickname "Defender of the Pad" for enduring such a long time without losing;
eventually I joined one of the local clans and I remember participating in some unofficial national tournament or something, and I really blew it, lost practically everything; that kinda burned me I guess.
2) Counter Strike Source - I don't care much for the regular game, but there's one mod that is really loads of fun - soccer. Playing 'FIFA' from first person is a hoot, I remember one time shooting a 'volley' after a perfect pass from one of my mates, it's darn satisfying.
Cheers for the nostalgia inducing giveaway!
