Too late now but you might have enjoyed A Tale In The Desert, a very niche MMO where social dynamics were key. As an extreme example, the players could hold an election for Demi-Pharoah and the winner was entitled to ban one player from the game. Not a character, the player. Campaigns might claim they would just never use this power. On the other hand if someone is a total asshole (e.g. building penis shaped art in your farm and deliberately distracting people from group efforts like moving bits of pyramid) maybe a DP campaign could just promise to ban them.
