People are so concerned with winning, that they fight tooth and nail to push their lynches through. You often see innocent arguing devolve into back-and-forth name calling. The amount of frustration and tension I have seen in some mafia games, outweighs the level of drama that exists on entire sites.
I have always treated mafia like a game, and I play it to have fun. It is becoming quickly apparent that other players are signing up for games and bringing down everyone else with their desire to win. In context, getting mad at each other because not everyone thinks the same way. I always had believed convincing others of your case and making compromises were skills good mafia players possessed.
Here are a couple suggestions that I believe the community should enforce on each other (not the adminstration), in order to make the environment more friendly. I am guilty of breaking some of these myself.
My two cents anyways. I am very interested in knowing if others share similar sentiments, and whether or not they have realistic solutions to the problems that are becoming prevalent in forum games.
