Educational Value- It teaches kids how to deal with money, and land, and how to strategically place things. I personally liked this app.
Sex-None. I mean, come on, a breeding cave?
Consumerism- Your child might be tempted to buy "Treasure" such as treats, gems, and coins, but I think you can set a lock on it.
Ease of Use- Simple. Drag-and-Drop
Privacy-The worst it can possibly get is visiting someone else's island. No comments, pictures, nothing.
