About The Urban Calculus, from BoardGameGeek:
The Urban Calculus (TUC) is a wargame and a playable, competitive systems model. It allows players to examine and consider some of the linkages between what is happening in the urban battle(s) and what the effects are on the civilians, infrastructure, society (of all combatants), global opinion and government will.
Initially 4 scenarios have been developed for TUC:
An introductory scenario - a relatively balanced potential conflict with the defender heavily invested in success
An asymmetric scenario – where not all parts of the model exist, and some linkages may be non-existent
Two linked alliance scenarios, one with an army defending its own city, and one where another one country is helping to defend the city.
The aim with TUC is very much to allow people to modify not just the values on the linkages between the different factors and capabilities, but also to modify the core model to reflect their own needs and concerns.
