I have a suggestion for a game, it is called werewolf. here are the rules.
at the start of the round, some people are picked for their different rolls, either seer (of which there is 1) protector (of which there is 1) villagers (of which there is number of players - 2 - (number of players - 2 / 5)
and the rest of the people are werewolves.
The game alternates between two phases, night and day.
in night, first, the werewolves pick someone to kill.
then, the seer gets to identify someone to be a werewolf or not.
then, the protector gets to protect someone from werewolf attack, so if the werewolves attack them. it doesn't matter, they're still alive.
then it is day, and everyone (including the werewolves) gets to choose someone to execute. this, like the werewolf picking who to kill part, is done as a vote, and when a majority is reached, it is decided.
After this happens, the person gets executed and their roll is revealed.
the round is won if either all the werewolves are dead (then the villagers win) or there are as many villagers as there are werewolves (then the werewolves win, coming and eating up all the villagers because their ranks are too few to withstand the werewolves attacking them anymore)
then the players on the winning team, either the werewolves, or the villagers (which includes one seer, and one protector) are awarded points, 1 point per victory, until a victory score is reached
the aim of the game is to be able to identify the werewolves and try not to execute someone who isn't a werewolf, by taking that risk, though, sometimes, the players are going to lie to each other to try and pretend they are not a werewolf, or sometimes, they may be helping their team.
