I reckon crafting and fully upgrading every item (where applicable) will take a very long time indeed. The bronze age alone would break the spirit of most people.

You'll need, I dunno, 300 bronze? That's 600 copper and 300 tin. That's, roughly, 1800 pieces of coal to smelt everything... which requires 1800 wood. That's a vast amount of time / resources.

Definitely a challenge. I wish you luck.
