‘Caveman Clash’: cheap primitive wargaming
Caveman Clash is a war game set in the time of cavemen and large now-extinct animals when battles were played out between small tribes using rudimentary weapons such as spears, bows, clubs and slings. The method of playing is very similar to that of
War Game, though the units and some of the rules differ.
Because we can reasonably assume that the battle tactics employed by cavemen were limited because of their equipment, language skills and so forth, the manual is short and only comes in one flavour.
