First time fighting Niten_Doraku, one of few Russian players who were especially friendly towards me, was on melee server. Him, Krivoruchka and some other guy were dueling when I entered, ten minutes later it was 3vs1. Wasn't pleasant experience but I managed to beat all three once which is quite the achievement considering Kpu's skills.
Niten wore that fugly red samurai armor back then and used Long Hafted Blade. He mainly played siege with same setup. Later switched to other weapons.
I thought Porthos is him but then I saw them both rocking Hello Kitty banner at the same time.
There are many forgotten legends of cRPG, some of them even I can vaguely remember and I'm pretty damn good at remembering everybody who ever spent more than a few hours playing cRPG.
Edit: I believe there isn't single player who still plays this shit who remembers Phyrex, who was hugely influential player back in the days.
