Is Project Spark limitless? I wouldnt be surprised if this is downloaded more times than Minecraft!

It´s not indie development when you have to pay royalties to Microsoft or whoever owns Project Spark to sell your Spark-powered games.

Fortunately, you're wrong. Project Spark is royalty-free. ^^ The dev themselves said so. You can do with your projects in Project Spark as you wish.
