For anyone else: it was a game creation toolkit <a href="http:&#x2F;&#x2F;welcome.projectspark.com" rel="nofollow">http:&#x2F;&#x2F;welcome.projectspark.com</a><p>Go watch the first video - imagine UE4 or Unity but way easier. Everything from world building to AI. Would have been really cool for teenagers to make stuff with, as you can get good results really quickly. You don&#x27;t even need a PC or a keyboard.
