3 questions:
Does only a single goon have the choice of loading guns, or can both choose 0, 1, or 2?
Can a goon gather multiple stacks of hated on a single night?
Does a goon choosing 0 bullets count as "loading guns", such that they can get stacks of hated loading 0 bullets if town chooses to shoot?
Yes to all of them.
I'm still trying to think of other rewards for Town. Let's break this down...(WARNING: Saying whatever I'm thinking)
So, there are 2 ways to interact with votes: Votes other people cast and the votes you cast.
We should also keep the theme of the game in mind: It's all on you. Your decisions shouldn't affect fellow Town members.
So, let's look at votes other people cast. Staying true to the theme, we're allowed to change how scum's votes are cast. Simplest method here is to say that a reward makes scum not be able to vote. Or not have their vote mean anything. Except...how do you individualize that? You can't make scum's vote go down lower than 0 (well, can you?...no. That would get confusing). And that reward would effect everyone else by having the votes scum cast against them also mean nothing. So I guess what you could do is say, "If you shoot an Empty gun, Mafia's vote count as nothing against you the following day."
Does this have any broken confirmations? X people on a wagon, at least 1 is scum. If they get ran up to the lynch number and don't die, they know at least 1 scum is on the wagon. Is that OK? I thinking no...So votes would need to be added somehow that make the claimed Townie not be so safe when he wants people to vote for him. Maybe giving scum a vote when they bow out?...No. That would stack up too quickly. Just against them? Eh, no. The people that dodge think they may be shot because they are pro town. Someone who is pro town won't have fear of being lynched anyway. They do have their vote though. Hmm...
Let's focus on the individual player's vote then:
"If you shoot an Empty gun, your vote counts as 2 the following day."
"If you bow out with an Empty gun, your vote counts as 0 the following day."
Or, let's make it a little more crazy:
"If you shoot an Empty gun, your vote counts as 2 the following day when voting against scum"
"If you bow out with an Empty gun, your vote counts as 0 the following day when voting against scum"
That may work...but seems unfun. Everyone claims what they did the night before and then just work it out from there.
Maybe bowing out isn't the best way to do this.
Maybe instead of bowing out you can "spin the cylinder". The chamber number for each gun is told at the beginning of each night. Scum can load more cylinders than just the one used that night. If you don't want to shoot the bullet, you can spin the cylinder. You can spin it any number of times. Each time you spin it, you take a penalty (probably 1 Hated). That way everyone has to shoot, but if you think you're in danger you can take 1 Hated in exchange for living. Wow. I think that a lot. Bolded it as a tl;dr version for anyone who doesn't want to read my thought process. I'll think on the statistics a bit more, then hopefully come back with something good.
