This is the one video game that makes picking fruit and then burying said fruit an addictive activity.
The selling point for me is that the game works with your Wii's internal clock. The current time of day and date is represented in the game. If it's too late in the day, the shops will close and people will go to sleep. The fish and insects found throughout the game depend on the season and the time of day. The activities and events are also based around the calendar with the residents celebrating various holidays throughout the year.
The online community also is pretty nice but it's also a bit difficult to get involved due to the friend code restriction placed on the game by Nintendo. I found working closely with a user created community helps this process but it doesn't make it any easier.
