Microsoft launched the Project Spark. A game-maker inside a game and they released versions for Windows 8.1, Xbox 360 and the Xbox One console. Project Spark is a “tool” meant to allow particularly gamers, developers and enthusiasts to build a game within a game. You can build custom worlds, characters, animations or movies.
Any games created with Project Spark can be shared with a community of gamers, where anyone can play in the games shared. As a player you can choose to start from a blank map or a pre-designed one, but no matter what you choose you have tools in your hands to customize all you want. Each element in game has its own brain to control movement and actions. Project Spark is free but there is content that could be unlocked using credits or money.
