Animal Crossing: City Folk is a great game. But why is it fun? Because this is all the fun stuff you can do!
1-Donate to the museum (of course)
2-Upgrade Nook's (I'm on Nookway)
3-Stick neighbors in pitfalls (They will get mad)
4-Dig for treasures (I still hate Gyroids)
5-Push neighbors around (They'll get mad)
6-Go coelacanth fishing (they only appear when it's raining)
7-Play over Wi-Fi! (The best way to have fun)
There is tons of more stuff but this is my best way to have fun!
