I am still playing this today.
I actually stopped playing for a while and when I came back to AC I was sad to have seen wolfgang gone.. He was one of my faves.
I find cranky villagers tend to leave my town more quicker than others... maybe because of my other villagers have an effect on this kind of personality? But for a while I lost interest due to some villagers that moved in which I wasn't too fond of..
But anyway I finally got two of my dream villagers for a price during trading for them and now I am sooo happy that I don't think I will ever stop playing this for fear of losing these two.
A few weeks ago Nintendo EU were giving out some codes to download a small app that allows the Animal crossing folk to appear when you take pics of real life things using the 3DS camera.
The app is called Photos with Animal Crossing. I may still have a spare code if anyone is interested but I don't know if it will work outside of the UK.
