I really think this is an age-appropriate community, while being a fun adventure type game the kids will enjoy. The graphics are very nice and customizable. What I don't like is that you can only get so far for free and then you have to become a member. Get the kids addicted and encourage them to ask mommy and daddy to pay for membership, I don't like this business model at all when directed to children.
The game is really set up for any age group, safe for kids, you see GM's in game all the time. The younger kids can't get onto the "filtered chat" servers where you can type, they can only get on the menu-chat safe servers. The characters from the movie are there, you'd be hard pressed to find anything that's violent or scary. Other great positives, it's F2P (free to play) and doesn't require any type of installation (unless you don't have Adobe Flash installed). Give it a try!
There is 24 hour live GM support and two types of servers to play on. One is chat with built phrases only and the other is a filtered safe chat server. Plenty to do with mini games and quests and its free to play. Awesome extension of Rango the movie.
