I have been playing this game for over 2 years, and throughout that time I have come across a lot of 'bad' language, although there is a filter to stop people from saying certain things, players have found a way to get through the filter.
On another note, it's a great game to make new friends and develop your social skills, as well as your money skills as it is based around that.
There are hundreds of mini games you can also play within the game, as well as walking around ourWorld, which has 8 islands.
It's safe to play, as you can change the communication settings and you also have the option to block players, so they cannot see you or talk to you.
You have a profile on ourWorld- which you can also change the settings to private, only friends, or public.
OurWorld can easily keep your child entertained for hours on end, without having to pay a penny. You can enter contests, go to events, go shopping, have a job such as working in Cake Mania or Flo's Diner, talking to people, vote at the catwalk as well as all of the minigames provided.
Paying the $50 a year gives your child a status of being a 'resident'. Once you are a resident you are allowed to visit the beach, sell things in the Marketplace, have a larger condo and get 150 gems a month, (you can also earn gems without being a resident). It makes the game easier for the child, as they can buy the items they wish without having to save up as much.
OurWorld also sells residency passes within the game for gems which you can earn without paying anything.
If your child is under 12, I recommend that parents should keep an eye on the child, as there can be some vile language, and a bit of violence.
Overall, I recommend this game for any age as long as parents are viewing the computer, it's great for developing skills and making friends.
