I've read some really cool stuff about it. I don't actually know what the hell the game is about, but there are two versions (GCN and GBA) that are compatible with one another. The game also runs off the Gamecube's internal calendar/clock, and runs in real time. So, if you're playing the game at night, in December it's dark and snowy in the game. If you're playing during the day in June, it's bright and hot in the game. Animal Crossing is going to be amazing.
