Yes, those rumors of Lego building a direct competitor to Minecraft were true: meet Lego Worlds. The sandbox game has launched on Windows through Steam's Early Access program for $17, and promises to do more than just let you sculpt buildings and fight off critters. You can alter the terrain on a large scale, and access ready-made drivable vehicles (including dragons) to get around the procedurally generated landscape. Not too surprisingly, there's also a big tie-in with Lego's real-world plastic bricks. You can play using a handful of old-school and current Lego sets, and more are promised down the road. Don't be surprised if you're eventually buying digital blocks at the same time as their physical counterparts arrive.
