The majority of this PDF is a timeline that provides the major points of the 10 years of alternate history that is the setting. There are two and a quarter pages of actual diary that gives a bit of feel as to what the game's mood might be like. The layout is stark and simple, but in a way that helps readability rather than hindering it.

With no real hint to the system or how the RPG will play mechanically, I will take it for what it is and give this a 4/5: a short and very simple pre-release setting teaser. If you're expecting anything game related or more extensive, you'd probably have to rate it lower, but that's probably unfair. As is common in alternate history circles, the work ends with citations and a call for collaborators and contributions of fiction to help flesh out the universe, but also a very basic note that there will be a "RPG skirmish table-top wargame" released "in the coming months."
