Project Spark will not require an Xbox Live Gold subscription, according to a post by the game's community manager Mike Lescault on the Xbox One Reddit forum.
"You do not need an Xbox Live Gold account to play Project Spark," Lescault wrote in response to a Redditors thought that an Xbox Live Gold subscription was required to play the game. "You will not need a Gold subscription to play Project Spark for free on any platform."
