TRIBES can compete in hunting runs. Winning tribe gets the hunted loot and all of the enemy tribes loot. You should be able to loot your dead prey for loose things such as a broken bone which "You tore the loose bone away, looks fresh!" and then you can sell it at a village. Villages should not be LATed. (Towns will be levels yes but no villages) villages should be possible to be attacked by predators and also possible for villages to be raided by tribes. Doing such an action of course, would mark all the tribe members as bandits, and when such bandits would enter a leveled town, the strong guards would attack them and selling things would be harder unless u want to pay off your "bad karma". (Since u can no longer sell to merchants u must find black markets and raid more villages for money.

I'll post more ideas when I get them
