sorry, however I am not entirely sure what the problem is. In tons of more official mafias, survivor is used very consistently with a half decent win-rate. As another example, I was survivor in kuro's mafia. In the right hands, people have a very good chance of winning.
Regular civilians simply need the civilians to win in order to be victorious. The Life and Death survivors need not only the civilians to win, but they need to survive themselves. Considering the majority of players will die, the chance of winning as a Survivor is less than half of the chance of winning as a civilian.
Why are you punishing these players simply for receiving a role decided at random?
either that night or the next night. If they don't use it that night, they can use it the next. They cannot use an ability 3 times per-night though.
So, let me get this straight. I know with certainty that you cannot possibly be online 24 hours a day, which means there may be a delay between when the Hourglass uses his ability and when you send the message to the Hourglass's target. If you're not active enough, or if the time zones simply don't work out by sheer coincidence, the ability would not work as intended. The actions of the night phase depend on your own forum activity and the time zones of the players involved. That's just stupid. The Hourglass ability should instead apply to the night phase after it's used.
see the start of the post. I will balance it to all my power.
But why are you hiding the full rules from the players? I'm fine with probability - at least you have something to work with. But you're literally not telling the rules to the civilians. I should hope I'm not the only one who thinks this is a problem.
