Properties are worlds where players can place models obtained from missions, achievements, vendors, and drops, after finishing the property claiming mission and interacting with a console. Custom models can also be built using Brick Mode with bricks from missions, achievements, vendors, and drops. Players can use Behaviors, a simple form of scripting, to bring their properties to life.
There are currently 6 properties: Block Yard and Avant Grove in Avant Gardens; Nimbus Rock and Nimbus Isle in Nimbus Station; Chantey Shanty in Gnarled Forest and Raven Bluff in Forbidden Valley. The medium Nimbus Station property, Nimbus Isle, is the most recent (and last property added to the game) property released on May 3rd 2011.
In Beta, there was only one property for each planet. They were medium-sized and quite plain. When the "Claim the Imagination Orb" test was added into claiming properties, they were upgraded and became more detailed.
After a player claims a property, that player may add Bricks, Models, and Behaviors inside of the Build Boundary. The player who claimed the Property may also change the name of the Property, as well as description, via Property Console. Once a player does any of these actions, a Mythran must approve the Property so that other players may visit. However, if another player activates the Best Friend feature with the owner of the Property, that player may visit the Player Property without a Mythran approving first.
