Well for me Doom 2 (still playing it on the net: Zdaemon)
and Quake 1, were the pinnacle of competitive 1vs1 deathmatch. No two games since matched the skill cieling that these two games offered.
I still recall with fond memories the time when a good friend of mine challenged Thresh to a duel in Quake 1(this was shortly after Thresh won that red ferrari) and the lame excuses that Thresh used to back out of the match.
So Im kind of hoping for that Holy Grail of a FPS deathmatch shooter, but alas the glory days of one-on-one deathmatches are probably over. Still doesn't hurt to hope right????
I have a nifty blue line!
