Cool minis, I like the bears. I see a lot of these movies involve half naked girls - cool. What rules do you use? Or are your minis for display purposes?
TT.
The Hammer studios movies were much about half naked girls saved from pterosaurs by heavily bearded grunting men

But they are still worth watching ! I am sure they are the primary source of inspiration for Mark Copplestone's figures.
As for the rules, I don't know yet. I will certainly use a simplified and streamlined version Lord of the Rings/LotOW.
My goal is to set up a participative game. Participants would first choose a clan, each one having strengths and weaknesses. I take from Rosny Aine (excellent book Quest for Fire and sequels) that there were a great variety of coexisting clans with a diversity of shapes and sizes, which allows the use of every manufacturer's models on the same table. There could be different types of Cromagons, Neanderthals, Australopithecans, Amazons, even a group of half intelligent baboons, and possibly abominable snowmen types !
Then a goal would be randomly chosen for each clan : hunting, rapt women or children, steal a fire source, take control of a mammoth dead body or a fruit area, or a cavern. Wild animals would be added for variety, and their moves determined randomly (or maybe moved by kids if some players come with their children).
Communication regarding the game (including alliances and war plans) would be limited to grunts, gestures and a limited lexicon of words taken from the Hammer films (Akeeta = this way ; Nahot = dead, ...). Of course today language would be allowed for discussing the rules or talking to the game master !
