A significant simplification of GMT&s popular Great Battles of History series this is a set of rules that means that you can play scenarios from many of the various GBOH games & their expansion modules Many of the more fiddly aspects of the system have been dramatically simplified (shock combat missile combat orderly withdrawal elephants leader activation) or eliminated entirely (routrally individual orders strategy ratings momentum trumping) The rules for SGBOH are the same across all the GBOH settings so there is no problem moving from game to game Scenarios also play much faster from 1-3 hours instead of the old 4 hrs & up Scenarios provided list approximate playing times as well as balance assessments for all the scenarios (of 53 scenarios 11 are rated as "even") Note that this is not a standalone game; ownership of at least one GBOH title is required Games that only require SGBOH rules (have SGBOH scenarios & game-specific rules included)
