Microsoft's free-to-play creation game Project Spark will let you jump in regardless of whether you have an Xbox Live Gold subscription, representatives have confirmed. After the recently-released Ascend: Hand of Kul required Gold, it seemed likely that Spark would follow the same path, but community manager Mike Lescault has set the record straight.
"You do not need an Xbox Live Gold account to play Project Spark," Lescault told a user on Reddit (via CVG). When the user pressed the question regarding its free status on Windows 8, still assuming Gold would be required for the 360 and Xbox One versions, Lescault maintained that "you will not need a gold subscription to play Project Spark for free on any platform."
Naturally, of course, it is still a free-to-play game. The basic set is included in the free version, and that set was used throughout the hands-off demonstration we were shown at E3. It will be adding new assets on a regular basis for purchase, but if you find some clever way to use existing assets to accomplish the same goal, Microsoft says that's perfectly fine too.
