There’s an art to balancing history and make it upness. 

But, when in doubt, my usual advice is to get a couple quick facts down and then go with what your gut tells you humans do as humans do it.

You’ll get it wrong, but you’ll get it wrong in ways that speak interestingly about how you feel about humans doing human stuff. Which is much more interesting than nerd-history-fuck-wankers like me getting it wrong in ways that are just fucking dull as 10,000 year old dirt. 

(10,000 year old dirt is fascinating btw. Tells us a lot about why early agriculture had such a big hicup in its startup. But, I’m pretty sure no one in a game, ever, has given even the tiniest shit about that.)
