I have fond memories of 2fort. Desperately wanting to play TF1 on a 14.4K modem from Germany - no European servers meant playing with 500ms ping, which made aiming completely impossible, so I took the pacifist route each time by picking the scout class and then trying to steal the flag unnoticed by coming in through the sewers. It worked sometimes when the server was only half full.
I would just play as medic and camp the enemy spawn room, infecting them as they spawned and watch as they passively infected their teammates. It was great fun (I have since grown as a person). It wasn't long before the enemy spawn rooms would instantly kill you if you entered.
