In my opinion a human vs human in a RTS/FPS game would be lame. You have to go and destroy other base and its equal on both sides. It will come down to who has the best shooters on each side.
Alien vs Alien would be funny to see, BATTLE GRANGER FTW!!!!
I think if trem went more for example CTF style like Halo where you ran around picking up upgrades and stuff [driving vehicles too] would be the only way you could have a human vs human.
Plus most maps wouldn't fit in anymore. games where its GUN ON GUN usually have BIG OPEN enviroments, with few walls and places to hide. Tremulous was just never built to be alien on alien or human on human.
Would be a cool mod though even if one server ran it
