Honest Opinion on Longevity left in Game.

there's still a lot of characters/buildings that could be released.. lionel hutz and the other lawyer the courthouse with the judge, the mob godfather, itchy and scratchy building with the creator, the bum that sued him (golden house and rocket car), the college with 3 nerds and the dean, apus brother, kent brockmans house and krustys clown college and house and literally heaps more that i can't be bothered listing.

possibly even introduce shelbyville when they run out of ideas or have tie ins with Futurama and more expensive buildings like the giant toilet.
