Free Realms was the only of Sony Online Entertainment's upcoming titles which was in a playable form at E3, and we had some time with it and found it interesting enough that we're excited to tell you that registration for the company's first foray into free-to-play is now open.

Free Realms is thematically a mixture of traditional fantasy and real world design, and it includes a variety of play possibilities including everything from playing mini-games to MMORPG-esque adventuring.

The game promises weekly and monthly content updates, regular special events and a great deal of player-led activities and customization.

"Free Realms allows you to do what you want to do, when you want to do it, in a lush, living, 3D world, filled with rich landscapes and fun wildlife," said a Sony representative. "From pet raising to mini-games like soccer and racing, or battling giant spiders and adventuring with friends – there’s always something new to see and do in the world of Free Realms."
