Mafia: general discussions.

No, Rudy, that's nonsense.

Please elaborate on what you mean by "that." If it's a modkill, where the GM understands it's a hint, then it might not be nonsense, because role elements are often revealed during the game, which contradicts the rules. In that case, the rules need to be changed, and I'll stop complaining.
if you learn from "What?", then "am I a lawyer or not?"

In the late game, everyone speaks in the voice of their roles anyway, so should we modkill everyone?

Exactly. You do it once, and that's it; the intrigue remains until the very end. Or, see "the rules need to be changed."
