I would at least think a trial period would be in order to see if anyone would actually be willing to play it, also "New players" wouldn't know what it is meaning they could try it out and find out they like it. Remember don't just eat one piece of pie, eat every flavor. ;P
To put it better, if they don't know the point it's pretty explanatory once you play a few rounds.
CT's Guards
T's Prisoners
CT's Jobs 1 CT is able to !w to enable what is called warden "Warden" As for what a real prison is like is the top dog of the guards who gives out the orders to the CT's and the T's CT's non-warden should be following the orders of the Warden but also keeping your distance away from the T's as much as possible, CT's must also keep track of all the T's to make sure they aren't "Rebelling"
T's You can follow orders and get "lr" Last Request which is a series of mini games, or simple rebel for a LR, or you could Rebel from the start of the match and kill all the CT's, perhaps even team up with your fellow T's and destroy the Guards to win the game.
