Mafia actually had a pretty good chance of winning till the miscommunication part on Day/Night 4 where giving the crystal ball and killing Arch at the same time didn't work.
Also, Arch asked me if there will be flavour when he gets shot and if he could write it. I said sure, but didn't use it because I wanted to keep it for when he gets killed and use his badass flavour of
"A bullet flies across the room and shoots Archivis right in the head. Since it was not a legitimate shooting, Archivis rejected the bullet because the body has ways of shutting those kinds of things out" during his death, implying that he can only do that in his dream, but alas, the second shot was blocked.
