You can vote for "No vote" and no one will be killed if this option wins. So yes, you actually "elect" No-vote. You can't lynch with most of the mob not wanting to kill, right?
As far as when the game ends, it's when all players have either won or lost: For example, if the game is still on if Moe has lost, but there is a possibility for Suzie to win. Moe would be a "Rogue mafia agent." He doesn't have to play if he doesn't want to, but since there's no way for him to win, he can do whatever he wants until he is dead. All players are done playing the game when they die, except possibly Hobbes. Until they die, they can play the game whether they've won or lost, unless there's no more chances for anyone to win. In this sense, the typical "Mafia outnumbers townie = mafia win" is nullified until the T-Rex is gone, but Suzie can be alive and this win can be fulfilled. BTW, Suzie does not count as a townie. Basically, the game should be over when the T-rex is gone and the mafia wins or loses. That's a good measuring stick.
For the mafia to lose, all of the mafia has to be dead, except Mrs. Wormwood, and for the mafia to win, the townies have to be outnumbered while the T-rex is dead.
For the townies to win, the mafia has to lose. Does that clear it up, or are there more questions.
I know this is complicated, and I know there's a ton of rules this time, but my main goal is to create a game where no one can really be trusted entirely.
As far as Rosalyn goes, she can win if Moe or Calvins are alive. Moe, more than anyone, needs a babysitter, but Suzie is mature enough to be home alone.
With Mrs. Wormwood, Good Calvin can be alive at the end. It's right there in the parenthesis.
You are correct about Mr. Lockjaw. When all townie-side Calvins are dead, he wins, then and there, regardless of anything else. He may still play until he dies.
Edit: Let me also say this: If Moe wins, he wins, but he probably won't win the prize unless he helps someone else win, too. So the incentive for an individual to play after he or she wins is to try to garner support for the prize. The hopes are that the prize will go to the individual that won that helped the most other people win, too. Does this make sense?
Any more questions?
