Great Fun!
Making enough money to pay off tom nook can be addictive and i find myself fishing for hours to get enough money to get the next house upgrade. If you want something that is gonna last a long time then this is the game you need, iv had this game for years and i still play it now and then.
Animal Crossing is a great game for all ages, it's easy for a child to pick up and play without them needing much direction form you. It's fun for adults if you just want to relax and take a break from more serious games.
Overall this game is very charming and will entertain you for a long long time.
