It's better if you share a town with other people (friends, siblings, etc.). It's a different kind of multiplayer experience. Sharing discoveries with other players was a big part of the fun. Things like saying "a blue cat just moved in!" or "I left a surprise for you by the post office" or "I just caught that rare dragonfly!" It's part of the game that has been lost on portable systems, since friends and siblings typically have their own portable systems (and own towns) and don't share the experiences in the same way.
