How about a series of roles that each carry more than one vote? E.g.
- Plebian- 1 Vote (14 in a game)
Senator- 2 Votes (5 in a game)
Consul- 3 Votes (2 in a game)
Total votes: 30
These roles would only define votes for the day time but each character would also have other Mafia game roles (Townsperson, Mafia or Cop). Any chance it would work?
