Microsoft held a 40 minute live demonstration of their free-to-play game making sim Project Spark, whose flexibility was shown off at E3 2013 when recreations of Limbo and Geometry Wars: Retro Evolved - among other games - where displayed.
According to Microsoft, the developers behind Spark have even managed to recreate X-Wing vs. TIE Fighter with a “fully functioning” X-Wing with every upgrade and The Force Unleashed.
Project Spark is going to be free for all Windows 8 platforms, including PC and tablets, as well as the Xbox One.
