These games are going to be fun, and It can work with 7 players, but I definitely think that for a truly amazing game of this variant we need to be on a map with more players(high teens, maybe into the twenties). A small issue with only 7 is that, if a knight is the first to die, it can become a little easier for the King and Knight to win(if the other Knight can convince the King he is in fact the Knight). I say this because If a Knight dies first, then it is 2(King and Knight) Vs 1 Vs 1 Vs 1 Vs 1... The other 4 have no idea if the others are Rebels or Knights or Traitors, so they will likely all be fighting and thus easy targets for the King and Knight. With a greater number of players(Lets say 15), you have 1 king, 2-4 Traitors, 5-6 Rebels and 5-6 Knights, leaving the question of who is who intact for a lot longer. Obviously I know that these 7 player games are just tests to see if the idea works, but I would definitely suggest starting to think of bigger games.
