Those aren't even old-school, really...middle-school perhaps.
I remember feuding with some of the more mouthy, arrogant members of the cK back in the old days, and discovered I had a talent for boxing that all but negated skills & health points, because back then, boxing was more about how you boxed than about your skills & health; auto-targeting didn't exist then. I found I could out-box a lot of players far more skilled than I, with way more health points than I, by strafing and using trajectory prediction when punching, not just trying to hit right at the target. (This was a skill I learned gaming as a 33.6 modem player against low-ping DSL & LAN players in QuakeWorld and other FPS games--I'm dating myself here!) So boxing was more about how *I* played, and not determined merely by stats.
I challenged several of the cK members to duels; Demosthenes, Qmefox, Rei and Leafren, easily defeating them all in player witnessed, unarmored, Aggressio-only ring-matches...with some, I still had more than half my health remaining after the knockout punch was landed...oh, how angry that made them, as I was an utter n00b in the boxing ring, both skill & HP-wise--but was a better gamer.
I was finally bested in a pretty close match by Vapz, who had WAY more HP than me (and was a helluva lot more polite and friendly, ironically). There was also a boxing event many years ago that I participated in...I met Marco at that event and shared a few words...but early on, I matched up with BlueFire, who cleaned my clock. Then again, BlueFire had probably the most HP of any player at the time.
That's one of the few legacies of mine that I'll never forget.
