I've probably played more Quake (I) than any other video game. Back then I used to play Team Fortress every day (for years). It is way better than either the TF for Halflife or TF2.
Does anybody else remember playing the 'build you player' maps where you got a limited number of points and could build you player from the ground up (speed, armor, weapons, grappling hook, etc)? You could even select the ability to summon creatures. You got blood points for knife kills that would allow you to summon Fiends and even Shamblers. Who needs an auto turret when you can summon a Shambler in the enemy base.
