At least The Simpsons: Tapped Out is constantly updating every day, so you never get bored, which is good, because more updates means I can expand on my collection. So far I have Apu, Krusty, Cletus, Homer, Lisa, Milhouse, Flanders, and Skinner. I still need Bart, Marge, and Grandpa to complete the Simpsons family category, which more than likely I won't unlock them until either level 11 or 12.
