In Tammany Hall, players help immigrants settle in New York, collect political favors from those immigrant groups, send ward bosses into Manhattan to secure votes, and slander political opponents. An election is held at the end of every fourth year, and the player who uses his power base best will be elected mayor. The Mayor's grip on the city is tenuous at best. After every election, the Mayor must pay off his political rivals by placing them in offices that they can wield to try to take control of the city. Every player is your friend, every player is your enemy.
GF9 mentions that the game will have "updated artwork", as shown in the promo image below, but doesn't mention any changes to gameplay.
