I would add to that some branch of the tech tree that lets you research basic medicine. Herbs, poultices, splints, etc. have been around for a long time.
More challenges like people would have faced: disease hits your animals and you just kill them. There's no contagion.
Some sort of leadership system where your head knocker influences in a negative or positive way what's going on with your tribe.
More natural disasters to overcome. Locusts, flooding, tornadoes. The occasional storm just is a bit underwhelming .
By the bronze age currency was certainly being used. The traders are fairly feeble. It would be nice to either have a greater variety of goods or be able to order up specific things for the next time he stops by.

I like this game.

some more suggestions:

- paths: it would be awesome, when the ground "reacts" on the villagers and paths show up in the grass - and villagers prefer to walk on this paths, when established

- fire place: grill meat. Bread is harder to craft than just throw some meat on fire. should be possible

- caves: would be awesome to discover caves as living areas or depots. e.g. in a cooler cave as depot food will last longer

- simple boats made of one Tree for fishing

- building on stilts in flat water making it harder for raiders

- raiders against walls: i don't like the idea, that raiders with knives can destroy wodden or stone walls. When they are wooden, they could use fire that spread out to every attached wodden building when not estinguished. stone walls may break but then a percentage of the stones should be reuseable

- wild bees for honey

- ...

this game has so much potential to be a long term fun. i would prefer some more historical accuracy (not in time but in workflows and structures)

I really just wanna kill more mammoths and have a enemy to kill!. I wanne go and destroy there town.! or towns

Personally, I'd like to see the Guard Towers shoot automatically similar to Age of Empires, but if that doesn't fit the realism of the game, then it would be nice if when you sent men to occupy the towers for defense, they actually stayed in there. When I man the towers, the men vacate the tower within 30 seconds of me sending them inside. Towers become virtually useless.
