15+? No way! If you feel comfortable with fighting monsters, than this game is for you.
Education: Children can learn how to save and spend money. Instead of one type of money, you have gold, silver, and copper. You can also learn about auction and trade.
Positive messages: Sure there are some cuss words, but if you are under 13, its best to join a family guild (a guild is like a club) The older members there will be glad to help you and are kind. I know my guild is!
Good role models: Sure, you can get drunk, but if you are, your avatar's vision is blurry, and you say things wrong. Example: If you become drunk, and you say "is", sometimes you say "ish" and sometimes you hiccup! Teaching you not to be drunk.
Easy to play: The game has easy instructions and helpful tips at first. Also, the holiday games are easy too.
Safety: There is a settings section for parents to filter words and such.
