John Welch is the designer of the game. Apparently this is John's first design for GMT but he's done a number of titles for Victory Point games including Cruel Necessity and Levée en Masse.
Some details below from John's BGG post. To access the full thread click on : A Terrible Beauty news
"The period 1918 to 1922 is a first important consideration as it bookends the end of the Great War in 1918 and the use of some of those veterans for service in Ireland but ends before the Irish Civil War gets going in a major way by the end of 1922. Choosing factions is always a challenge. Currently, I'm using the British Army, the RIC (including the 'Auxies'), the IRA, and what I'm referring to as the 'Republicans' (those Irish that wanted Statehood and were prepared to 'deal' with the English to get it). In a two player game, the British Army and the RIC would be grouped together as would the IRA and the Republicans. The four player game is much more of a challenge as all the four factions are working (to a greater and lesser extent) in opposition to each other. I want the Operations for each faction to reflect their particular goals. ....... the goal of the British Army is to maintain order, keep English public opinion up, AND get the most favorable treaty possible. Treaty negotiations are an integral part of the game and can lead to some "interesting" deal making with the Republicans. Public opinion is the 'currency' the British Army player has to deal with and the actions of the RIC were often at odds with that."
