Project Spark

 was a game creation video game for Windows 8.1, 10, and Xbox One. The game was announced during Microsoft's E3 2013 press event, and was launched as a Windows open beta in December 2013, and an Xbox One beta in March 2014. On May 13, 2016 Microsoft announced that Project Spark would no longer be available for purchase and that online services would no longer be available as of August 12, 2016. Although no longer available for sale, players can continue to play offline so long as they downloaded local copies of their, or other player made creations.

Gameplay
Project Spark is a digital canvas that can be used to make games, movies and other experiences. A player can download other user-generated content, remix the content, or create content of their own. A player can use the Xbox One controller, keyboard and mouse, the touch and Kinect devices to build experiences. Kinect can be used to animate models and record audio. The created environments may contain mountains, rivers and cities. The player can also create events, such as the battles between characters. created elements and objects are able to be shared with other players.

Players choose whether to start from a blank map or a pre-designed level, but always have the tools to customize the topography, add animal behavior and plant life, and programs for specific objects, like a rock that bounces when a player is nearby. The topography is changed by pushing and pulling the land, digging through the surface after changing the view to adjust a wall or create holes. All this added to the soil reacts to the circumstances, like the grass that covers the floor and vertical surfaces become rocks.

Development
Initially the game was supported by microtransactions, but in September 2015, Microsoft announced that the game would transition to a new model of "creating free and open" with which all the downloadable content would become free for both new and existing players starting from 5 October 2015 as part of the transition players who have paid for such content, after up to one month before the announcement were eligible for a refund on the basis of what they had paid. Microsoft ceased production of all downloadable content, including future episodes, after the last update was released
