Looking for advice: RL Mafia game

[BBmolla]

I don't like to have more than 4 power roles with 13 players because it ends up taking too long. Let that sink in.

Play a very simple setup or 2RoomsandaBoom instead

Also, I guarantee at least 30% of the players will be one of the following:

• Unengaged and on their phone
  
• Lynching someone because they have a hat on (or one of many other dumb reasons that are irrelevant)
  
• Confused about their role and have to ask you how it works
  
• Speak up day 2 to ask if you started playing
  
• Lynching just because
  
• Not speak, just vote

If you're fine with having the above, then all fine and good.

I've only ever had the correct amount of seriousness it would take for a game like this at the Mafiascum meetups. Even when I host mafia nights you always have a couple of players who do the above.
