Mafia: general discussions.

But the game was in the mafia's hands, and they somehow managed to lose! So, the town isn't as strong as it seems!

Why didn't you think about why the game was initially in the mafia's hands? Successful kills, unsolved clues, infighting among the vigilantes, a lot of arguing about roles, and inactivity from the town (mainly Gil just loafing around). Why did the mafia ultimately lose everything? It was because of these undeniable comparisons, which reduced the list of possible roles for the town to a minimum. Nothing too complicated. No super-subtle gameplay. A combination of circumstances + an overload of undeniable information for the town.
