Work with your team to win, then stab your team-mates in the back!
I'm going to have a go at this, with the help of DaaMaan64. This is a normal mafia game but there is no mafia "powers" of sort. All players have will have items from Mario Kart Wii. They can be used on same team or opposite team. Use them to protect your team, target the green player, or protect yourself.
There are two teams, Red Team (Mafia) and Blue Team (Townies).
There is one green player.
Rules:
The role of red/blue is to defeat the other team.
The role of the green player is to cause mischief and strife in both teams.
Last remaining peoples in team win.
If green player remains, he/she automatically wins.
With the exception of the green player (who would automatically win if left undetected), everyone votes who to be best player at the end of the game.
All players will have 3 points.
Deplete points and you die.
Day/Night votes kill automatically.
The Green Player gets two items. Everyone else, one.
Items:
Red Shell - Removes one point from nominated person. Same day use.
Blue Shell - Removes one point from all opposing team. All weapons ineffective except Star and POW.
Banana - Protects against all offensive items except blue shells and POW. Single use. Deploy for next day. Will expire if deployed and unused.
Mystery Box - Removes one point from nominated person.
Coin - Restores one point to nominated person. Same day use. Alive players only.
Identifier - Allows user to find out who has what type of item. (e.g. "Who has the Blue Shell?"). Single use.
Cloud - Removes 2 points from owner unless one point is used to transfer to someone else. Cloud attacks after second day.
Team Specific Roles:
Lightning - Cancels all votes except for one nominated person. Can be used on same team or opposing,
Star - Invincible to all attacks for 2 days.
POW - Randomises all current votes and night actions.
Boo - Swaps the item of one player for another.
