The rush to build virtual worlds for kids is on. With spaces like Webkinz and Habbo Hotel dominating, and Gaia Online coming up fast, Mattels Barbie Girls which launched in April has its work cut out. Barbie may just have a little more to worry about now though, as she chases the preteen girl market, as details on Sony's new "Free Realms" emerge in this NYT story. Free spaces filled with horses and puppies and no doubt princesses and pretty dresses as well.
Free Realms is basically aimed at children, especially girls. The game will be free to play in general, but will require paid membership for access to special zones and activities (hence the term “velvet rope”). In terms of microtransactions, players will be able to buy virtual in-game items like pets and clothing à la carte. And there may also be advertising inside the game.
Free Realms is due out this winter on the PC.
