I love Animal Crossing =D! I remember renting it, deleting everything on my memory card just to have a save file, becoming frighteningly obsessed with it, getting sad when I had to return it, then getting it for christmas and getting re-obsessed XD.
It gets kind of boring after you have your house set up the way you want it though. However, I never paid off the debt after the first house upgrade thingy. After you pay that off, do you get more upgrades or what? I think I remember seeing screenshots of people with huge houses when the game first came out, but I don't know how they got them that big.
In short, animal crossing owns, and if I don't get Wild World for christmas I'm going to... uh, be very very sad. Uh huh.
Tom Nook is sexy. </creepy sarcasm-ish-ness>
