Minecraft is totally dominant in the sandbox game world, but Microsoft's recent acquisition could soon have a competitor in the shape of Radiant Worlds and Smilegate's SkySaga.
Billed as an "endlessly evolving multi-player, sandbox online world, that is as beautiful as it is ground-breaking," the game does appear to have many similarities with Minecraft.
In SkySaga no two heroes are alike and no two player journeys the same, either working in a team or questing alone. The game world is a procedurally generated voxel landscape, filled with treasures to find, dungeons to raid and resources to gather: dig for minerals, chop trees for fuel and construction, hunt animals for food and build shelters from the elements and the dangers of the night.
Each player gets their own Home Island floating in the sky. Everything built on a Home Island is persistent and players can invite friends over to visit and maybe start an adventure together.
