Huh? Bandai began adding expansion areas when they brought out the Tama-Go last summer (June/July/August 2010.) Currently, in addition to the main MusicCity areas, we can go to Flower Hills Park, Swirly Sweet City, and Forest Falls.
Hahaa, Honey. There is not a limit of points and they've already expanded it. However, if you donate 1million points, then you get an array of gifts, the biggest being Truth Of Kuchipatchi.
