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.
The retail package will deliver an incredible collection of premium content for $39.99, including the first sci-fi pack “Galaxies: First Contact,” the warrior champion Sir Haakon “Hawk” the Knight, “Champions Quest: Void Storm,” the first episode of an epic campaign adventure, and more. The “Project Spark Starter Pack” will provide immediate access to some of the best paid content, features and add-ons in a single package. All of the content included in the disc version will also be available digitally for Xbox One and Windows 8.1 on launch day.

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.
