Ok, so I don't have a ruleset for this yet, just a really good idea.
3 players are the "Council".
Each player gets 5 votes.
Instead of voting in thread, a player can buy off the Council with his votes, asking them to do any number of things. Really want to edit that post? That'll be 3 votes! Kill that guy? That's 4! etc. Alternately, everyone gets a normal lynch vote and a few votes to buy off the Council, but this is better from a "Cost to your actions" standpoint.
Councilmembers have to pay votes to do things for players (I'm thinking each one has different costs, so they can lie about what things cost to draw votes from other councilmembers). These prices will be hidden from everyone except the councilmember themselves. They'll vaguely resemble roles, but generally be more thematically intrigue-ey.
Players can also bank votes to save for later days to go after the really big ticket items.
Councilmembers win by accumulating the most votes throughout the game. The councilmember with the most wins, the second most draws, and the least loses. They are bulletproof and lynchproof, and have no lynch votes themselves. Players may PM councilmembers and vice versa freely.
Thoughts on the idea? Alternately, I considered forcing the council to agree on actions, but this seems like it'll generate more conflict.
