The most fun that you can get out of the game is to take your character and visit other people's towns.
The most fun that you can get out of the game is to take your character and visit other people's towns, or allow them to visit you, and this is where the game really comes to life. It's not an easy task to get started, visiting towns, but when you have found people with the game (most likely on the internet) who wish to play online, it's great. You can chat away using the on screen keyboard and do whatever else you like really. Get new items.
Though that is about it. The technology behind animal crossing is advanced, and opens up the way for new similar games taking advantage of the online WiFi connection, hopefully Animal Crossing 2.
