- Trading with humans, inlcuding exchange of slaves and "cave-men". Sometimes exchanging warriors could be a sign of trust and friendship?
"what i got on me" trading with anyone is in there, and trading with bands at their shelters (same idea, more stuff) is planned. also, there are NPCs who specialize in trading and have lots of stuff to trade. they are what's left of "the store" in settlements from the original version. they will probably get watered down, and not carry every object in stock. There are also plans for true realistic trader encounters, with wandering professional traders. even at this early stage before man had settled down in one place year round, there's lots of evidence of early trade spanning surprisingly large distances.
another NPC specialty is warrior. you can hire warriors from "friendly" bands. but they are quite expensive.
attack to subdue is in. capturing prisoners in combat was turned off while i dealt with a tactful way you can enslave, kill, rape, and/or eat your prisoners. that design problem has been solved, and it "Looks like caveman is back on the menu, Boys!" so to speak.
gift exchange is in there, but troop exchange is not. but its a perfectly valid action. i think that one's going on the todo list.
Just to clarify: in the game, the cavemen are humans. All PCs and NPCs are species homo sapiens sapiens (IE us). the closest you get to a "traditional" caveman is Australopithecus, a giant gorilla-like ape. But Australopithecus is an ape, not a hominid (early species of man). While the time period setting of the game could include the era when homo sapiens sapiens, neanderthals, and denisovans were all present at once, homo sapiens are the only hominid species in the game.
I have thought about adding the ability to play earlier hominid species, but it would just limit your skills, intelligence, actions available, and your personal "tech tree".
i suppose for thoroughness i ought to add the odd encounter with other hominid species that existed at the same time.
