I think this site is great for tweens to play on. Kids can buy and obtain different types of clothing, pets, and accessories, hair, and play games. The games are very simple to learn and play. By playing these games, players can earn "stars" (currency). They can learn to save and spend responsibly. Each player owns their own home which they can decorate with furniture and upgrade by buying a new design.
Although this game is free to play, lots of the features require paid membership. Most of the time, the players with paid membership get better options/stuff (home options, clothing, pets, etc). So buying a membership would make your Fantage experience better. However, the membership doesn't last forever, and you would have to buy the membership again if you want to still be able to use the member features (if you buy something when you are a member and your membership runs out, you won't be able to use that item until you get a new membership). This is what eCoins are for on Fantage. You can earn eCoins on Fantage by watching advertisements or simply buying them in large amounts. When you buy eCoins while you are a member you get twice as much. You can use eCoins to buy anything on Fantage, even paid member items if you are a non-member. The eCoins are harder to get than stars, but they can buy anything, while stars can only buy non-member items (if you are a non-member).
The chat is monitored by admins, so there won't be any explicit language, However, the admins can't always keep up with the new words people are making up to get around the no swearing / no sexual activity rule. That means that people can still easily say or do inappropriate stuff on Fantage, just with different words that everyone who uses Fantage have caught on to.
