Setup: Will of the People
6x Vanilla Townie
2x Mafia Goon
This setup is nightless. Therefore, the EV is exactly 50% according to the Nightless Expectation Rule.
Instead of the typical majority lynches, lynches are decided by using the condorcet system; see this link for more information. Basically, the Condorcet winner is the one who wins the most 1v1 matches against the other candidates. One of the advantages of this method over simple majority voting is that it accounts for 2nd, 3rd, etc. picks as well as one's top picks. So if you think Tom and Jerry are both scum, you don't have to choose to vote one over the other. (You still have to rank them, but inverting 1st and 2nd place is probably not going to make a huge difference in the long-run.) Instead, you can simply have both towards the top of your list, and you can rest assured those preferences are being accounted for.
(Note: As determining the winner is generally tough, you don't have to do it yourself. There should be online calculators for this thing; here's one I found from Googling.)
Because attempting to track all of these votes as the game progresses by hand is rather annoying (and difficult), the moderator instead only tracks the number of players who wish to end the day earlier. Once the day is over, the game enters a special Twilight phase where players send the moderator a ranked list of their choices for the lynch, including themselves (i.e.: it must have the entire player list), (with the person they want lynched most at the top). Players that fail to submit a list in time rank players in the order of the player list (i.e.: not random). The moderator then determines the Condorcet winner (likely using a calculator of some sort) and posts the lynch as well as everyone's lists. In the case of a tie or an undeterminable winner, no lynch occurs, but the moderator should still post everyone's lists. Then, the next day begin. Standard win conditions apply.
If 50% EV is too high, we can change the setup's composition. We could do something like 7 town and 3 scum, which has an EV of 40% according to the Nightless Expectation Rule.
