I think both of you (@Elfryc too) would enjoy sing the Otzi the Iceman film. I watched it last night and you don’t need to speak German to understand it. I think it was reasonably accurate and it would do a good job of helping put you in the mindset. It shows late Neolithic and early Bronze Age people. I might add, they don’t wear those silly linen tunics

The only inaccuracies that I saw were very minor, such as people keeping their bows strong all of the time. I would warn you that it isn’t for children… It definitely has the adult DLC LOL
