What does this mean exactly? Well it means that parents can rest easy knowing that these two games are fun, informative, and free of questionable content. If your kid plays either of these two games, you don't have to look over their shoulder to police what they're doing. The game takes steps to keep your kids safe and to make sure they'll have a good time too!
Other recipients that weren't from the online MMO category included EA's Spore, and Guitar Hero On Tour, so it certainly speaks to the quality of these two titles for kids when they're put in that sort of company.
