E3: Xbox One upgrades Project Spark DIY game creator
Microsoft's Project Spark is a concept that lets players become game-creators.
When it was first announced last year for Microsoft's Xbox One console it generated a lot of buzz.
It's now been out in beta for a few months - with players creating interactive content from a blank canvas that they can populate with a number of downloadable objects, from trees and rocks to monsters and weapons.
So what kind of worlds are they creating?
The BBC's North America technology correspondent Richard Taylor spoke to Brad Shuber, the title's art designer, at the E3 expo in Los Angeles.
