This is really cool, I've always had a soft spot for the Unreal Engine. But it reminds me once again, why the hell does Flash even exist any more? While I get the whole "HTML5 wars" thing, I've done standards and I know how those get mired in the muck, but if you can write a game engine with this level of performance, writing an open source 'flash' equivalent should be pretty doable right? And open source and open tools and don't bother with the quacking of the standards guys, just focus on something that works right?
