I play ACCF maybe.... once or twice a week for about 1 1/2 hours. I don't play it that much, unless my friends are on or it's a holiday. In that case I will stay up all night. My playing time's pretty inconsistent.
Back when I had Animal Crossing games to play I used to play the Gamecube and DS versions for like 30 minutes a day. When I played online on Wild World, it could range from like 1-5 hours, maybe more.
