Project Spark Transitions into Free Incubation Engine Next Week

On October 5, Project Spark will transition from its microtransaction model to a free and open creation engine. This will automatically unlock previously paid downloadable content for new and existing Project Spark users. Microsoft will pivot from producing DLC and active feature development to encouraging more user generated content and opening the Project Spark experience.
For those who don't know what Project Spark is...
Project Spark is a powerful, yet simple way to build and play your own worlds, stories and games.
Experience the ultimate interactive playground, delivered as a free digital download with many options for enhancing your creative experience.

I'd forgotten about this game since at the time I was running Win 7 - I guess it will be worth checking out after 5 October.
