Summary: My daughter had this game previously and loved it, so I thought I would get her another one. This game has an internal battery that lasts about 10 years I am told. When it dies, you can not save any games and have to start new every time it is turned off. This game was not that old and the seller did not mention anything about it not saving, so I bought it. Upon receipt, my daughter discovered it would not save her games.
