*First of all, sorry for my poor English
Personally I think adding more characters now would have the main issue of current max game sizes (12) being too small.
I play this game very often in real live and sometimes even with groups of 30 people. What I notice, since I play leader a lot, is that the smaller games (8 to 18 people) do not need any of the characters from any of the expansions (New Moon, The Village or The Characters) to make the games interesting. The people who play a lot will notice that using The Village expansion can also add a nice twist to the Original game.
So on one hand I do not think adding characters would change much to the game, especially since the characters which would or could be add will probably be very specific ones, since I know some characters just require larger group or are otherwise way to overpowered. When counting all the non-ordinary villager roles in only the expansions together, we come on 23 EVs and speical werewolves (26 because some share a collective role). Looking from that regard, it is surely possible to add some of these. I listed some of them directly below this passage, if you want to read them. Keep in mind that these roles are mentioned with the idea of a still small game in mind (max 18 players).
Un-used but possible EVs for boardgamearena:
The Scapegoat (If the village can't agree about whom to eliminate, the scapegoat is eliminated. Nevertheless, he can decide about who can vote the next day)
The Idiot (If he is chosen by the village to be eliminated, he stays alive, but he cannot vote anymore)
The Ancient (He can resist the first werewolf's attack, but if he is killed by the witch, the huntsman, or the villagers, the villagers lose their powers)
The Simple Villager (On the two faces of the cards, there is the illustration of a simple villager. So, everybody knows that it's a simple villager)
The Stuttering Judge (Once in the game, he can decide that there is a second village's vote by a sign that he had shown to the animator during the first night)
The Fox (Each night, he can choose three players. If in these three players, there is at least one werewolf, the animator gives the fox a positive sign and he preserves his power. But, if there aren't werewolves in these three players, the animator gives the fox a negative sign and he loses his power)
The Devoted Servant (The devoted servant can, whenever during the game, exchange her card with the village vote's victim's. She plays this character until the end of the game)
However, another problem with large game is, as you might have guessed, the playtime. Some normal games of 12 people now take around 20 minutes, which is already a fairly long time. Also keep in mind that this time is experienced as to be longer for people who got eliminated earlier in the game. For my experienced, games with 18 people take around 30 minutes, but games with 30 people easily can take an hour. What I want to make clear from this, is that a long playtime will be unappreciated by most casual players, which in turn means most of the un-used roles will never make the cut for boardgamearena. Thought I think the ones I mentioned above fit perfectly (if balanced well with other EVs) in games between 12 and 18 players.
There is even much more depth to the Original werewolves game than some may know; like event cards were every day a special condition is added to the game (for example a womens party took place, so all the women who are playing are too hangover to come to the voting the next day, and thus wont vote for that day). Or The Gyspy who can ask a spiritual question once a night, with all player will hear the answer on (for example "are all werewolves male" … "yes/no"). But I'm going slightly out of topic here haha
All and all I think some new character would make this game even more fresh, since more different character combinaitons can be used. Even other mentioned characters here like The Pyro, The Raven or The White Werewolf could be included without the need of The Village expansion (however, this needs to be done carefully, since I tried this something in real life, but this often turned out to be really unbalanced, since Vagabonds keep The Pyro and The Raven from being too powerfull. Same for special roles against The White Werewolf). Yet I think a max of 18 people should also be the absolute max for playing online. We regular players all know how frustrating it is if other players are not talking, talking a different language or are simply afk. But until that time, I hope we can have a great time with the roles currently included in the game!
