Well, if it was an RPG it'd be for the same reasons a game like Harvest Moon is, but while that's been marketed as such I've never seen Animal Crossing get the same treatment, so it's staying here unless someone disagrees.
Anyways, considering it. I only rented the GC game and meant to get the other installments at some point, but this sounds like the best in quite awhile and buying digitally would work really nicely for a game like this.
