Okay, here's my random ideas for a few gamemodes
TDM - be able to set the teams between 2 and 4, as to stop those R/S players from whining about "runners"
RTM - rambo team match, teams should be from 2 - 4.
make the gamemodes Death Match, and Team Match.
In death match you can set whether the game is rambo, deathmatch or pointmatch.
In teammatch you can set if the game mode is team deathmatch, ctf, htf or inf.
