I just read MGPP, Space's TDM mod, CityRP and CityRPG (those were the 4 things that came to my mind as using minigames started from readable scripts) and I still cannot figure it out, For now it looks like ill need to create a servercmd to put myself in the mini, instead of being able to select it from the minigame list.
The object of this minigame will be to run on a dedi and not be dependent on a player.
