You know in real life, (especially corrupt cities like Vice City) you have mafia... and where you have mafia you have hitmen. I think there should be a set of commands for a new hitmen class. Like policemen, the can "want" a player sort of. Maybe a command like !hit <player ID/nick> <amount of money>, to put a hit on that persons head for a certain ammount of money, and the ammount of money offered automaticly gets transferred from "hitter" to the hitman. Then the hitmen class can go out and kill that person.
Pros: a fun new way to play the RPG
Cons: it may give the citizens too much power and may more revenge killings and random killings occur. They could just type hit right before they kill them so they get money. Or it may open up new ways to money cheat.
