The Project Spark Starter Pack will begin to hit retailers on October 7 in North America, October 9 in Asia, and October 10 in Europe. This is the Xbox One retail version of the game that is presently in beta for a variety of users, including Windows 8 users. At present, it is slated to sell for $39.99 (USD) and include a variety of "premium" content in one package.

Now, Project Spark itself is free to download on Xbox One and Windows 8 but this pack is essentially a collection of the premium micro-transactions you can get. If you're already playing the game on either platform, you will get an update to your game that will keep your credits, creations, and favorites intact.
