If you at least occasionally touch video games, you should know the Unreal Engine. Pretty impressive and powerful thing. The guy who made the video above combined it with a pony.
And it looks very good. It might be just a first tech demo with a pony walking around... For now.
Of course he plans on further developing it.
Look at its current state and imagine where it might lead to. What would you like to see being done with it?
