Angel Fish: I am convinced rules designed to limit what people can say is not going to work. It will just degenerate into not revealing info you should be able to. Think of a normal game where the cop can't reveal his role.

And the town crieth, "Why sketch?" Because I'm a...oh. I can't reveal my role. Just trust me on this one, lynch IS. I like games with no straight up townies. Look at dune mafia, how many fremen were there? They all had an ability (that was an unknown liability in a lot of ways) and it was much fun to see the town boggle at the possibility of all these night killers running around.
I think the key to a good game like mafia 3 is the barely useful roles. I believe Antrax mentioned in another thread that a role should never be to important to the overall game. I totally agree. You can still have big effects, but be sure to balance them with their unlikelyhood. Look at mafia 3 again, we MIGHT have lynched neo the first day...maybe the chance of the lynch machine killing people eventually maxes out, maybe it doesn't...I have no idea, but I LOVE thinking about it.
