This is a simplified, summary version of Liber Militum: Tercios. Using Brevis Editio is a great way to get started if you have no experience in wargames, or if you want to try out the game without adding too much complexity.
As game developers, we believe it is our responsibility to design rules that encourage the player to have a pleasant experience and enjoy recreating what is intended: epic battles, historical or fictional, that leave the unmistakable flavour of the era.
The game table must be visually appealing, reminding those of old paintings that recall famous battles. To achieve this we don´t believe that adding too complex rules is necessary as we consider, of utmost importance, game flow over exaggerated realism. However, Tercios provides enough complexity to always make victory a challenge.
Tercios is a large-scale battles wargame, as every unit in the game represents the huge formations that often comprised more than a thousand men. Therefore it provides a greater abstraction than other games, as at this scale of war the individual actions of soldiers are irrelevant, as it is the action of the entire unit that matters.
