Microsoft announces that Project Spark is now out of beta, focusing on the Xbox One edition, though this game development system is also available for Windows 8.1 PCs as a free download. They note this does not mean this is "finished," as they view Project Spark as "an ever-evolving service shaped by the community." In addition to the free-to-play game, they also offer a premium Starter Pack with additional content. Here is a new "What is Project Spark?" trailer, we have this video featuring executive producer Saxs Persson explaining what is included in the Project Spark Starter Pack, and here's part of the announcement:

Project Spark is an experience like no other that aims to democratize game making by giving everyone easy-to-use tools to create, play and share their own creations with others. You can instantly play tens of thousands of user-made games, remix a pre-made game, or hop right in and make your own game with tools including 3D sculpting and a visual programming language similar to what the pros use, made accessible to all.

Project Spark is free-to-play and is available for download now via the Xbox One and Windows 8.1 stores. Add-on content can be unlocked by using in-game credits earned during play, or by purchasing tokens to buy add-ons immediately. Fans will see a host of new content available on launch day including sci-fi skin, adventure mode, champion features, creation enhancements, and multiplayer mode to inspire all new gameplay.

Those brand new to Project Spark might want to check out the Starter Pack retail disc that includes $85 worth of downloadable content for $39.99 (USD).
