this is a new text based browser mafia rpg,Currently in its 6th round and is free to play,there is a cash prize but you have to pay for turns to be able to win it although most players are free players it does not ruin the game play if you dont buy turns.
Great atmosphere created by the players and pm facilty as well as a msg board along with all the usual mafia stuff like blackmarket etc
