Ugh. Rock-brain number say good hunter or bad hunter. Now rock-brain number watch you buy mammoth tusk, pay later. Tribe news say so.

Big trouble for cavepeople who buy now, ugh, pay later! Fire-rock, the thing that says if you good or bad with mammoth tusk trades, now change. If you say "Me pay later" for new club, Fire-rock see. If you no pay, Fire-rock get angry. Harder trade later for cave, furs, maybe even mate. This mean you need hunt good, gather lots, and trade smart. No take too many shiny rocks, or Fire-rock make you sad. This new thing make sure everyone trade fair. Good for strong cavepeople, bad for lazy cavepeople. Oog, strong hunter with many kills: "Me always pay mammoth tusks on time. Good for Oog." Boog, berry gatherer with empty basket: "Boog scared. Boog owe many tusks for new spear." Chieftain Rockhead of Big Cave Tribe: "This good. Make cavepeople trade fair. Strong tribe good tribe!" Story by Grog from Caveman Talk Fire, on the scene.
