Xbox One game-building game Project Spark has attracted more than one million players.
The figure was revealed at E3 2014 by Microsoft, in a video that showed how users can create levels on different terrains such as desert, jungle and snow.
As well as 3D levels, players had also created 2D side-scrolling adventures and board games using Project Spark.
Games created by users can then be played with others through versus or co-op.
The trailer also featured a cameo from a famous game character, Conker!
