It's pretty cool that you can use the engine in Total War: Rome II to make short documentaries like this. In this trailer, historians including Bettany Hughes and Mike Loades examine the disastrous Battle of Teutoburg Forest through the lens of Rome II. It's a neat piece of work using all in-game assets. I just wish some developer would combine the historical accuracy of this genre with something more accessible, like a third person adventure, without turning it into a repetitive hack-a-thon like Ryse.
