My son (12) has been playing within the Lego Universe for the past month. It's an MMO. There is a free membership available, and I'm considering buying the paid membership for him for his birthday next month. On a safety level, players can't use their own name. They pick from a list of funny combinations of words as their player name. There is a chat, but that isn't available for free members, so I'm not sure how that will go if my youngster gets the paid account. There is a forum just for parents on the Lego Universe where they will answer any and all concerns. The FAQ for parents is comprehensive and made me feel that they would do their best to keep their online world safe for kids to play. Since I don't play it myself, I asked my son to write a review:
When/if he gets the paid account, I'll let you know how that goes!
