Here at Gamescom -- as you might expect -- you're gonna see a lot of games. Not all of them are finished, but even the beta versions come with complex worlds, and shiny new physics engines. Amongst all of these creations, jostling for our attention, was something a little different. Something we heard about back at E3 initially, and something we've been itching to see in action ever since -- Project Spark. We made sure we got to have a look at how it works, and some of the new features. So, click past the break if you want to know too.
