If you’re hosting a Mafia game, you can’t participate in it. That would entirely defeat the point of the game.
As highlighted in the Mafia Hosting topic, it’s required to contact a Moderator (preferably me) to get the go ahead before hosting.
I highly suggest that you read through this topic:
As well as other Mafia topics on the Boards before considering hosting a game.
If you wish to host a Role-Play based off of Overwatch, you can feel free to do that in that sub-forum. I get the feeling that’s really what you want here.
If you feel like you still want to host this game, take a look at those topics, and PM me to open this back up.
