I'm currently calling it King's Court (for lack of a better name).
Basically the court consists of 9 characters, each of which is either Good or Evil. Think of it as kind of their own game of Mafia, but everyone is uninformed and either side could be the majority.
Each character has action cards that players can play. Some action cards are Good, some are Evil. A Good character has more Good action cards, while an Evil character has more Evil action cards.
When players play action cards, as well as the special action on the card, they will cause the characters to attack and finally kill other characters.
At the end of the game, the side with the most living characters (or, in case of a tie, the side with the fewest dead characters) wins.
Players then get points for having played cards associated with characters on the winning side (regardless of whether the character is living or dead, or whether the card is a Good or Evil action card).
At this stage I'm thinking it will take 2-4 players, and will probably be worst with 4, but I'll take anything in that range.
If I get any interest, I'll release the full current rules and characters/cards.
