I was thinking the same. But maybe the changes go further than just adding new techs to the beginning of the tech tree. The "screenshots" are only thumbnail size, so no way I could read anything. Who knows what gameplay changes remain even when you select Ancient as starting era..
Slowed growth, mythological creatures is exclusive to Prehistoric era.
Hunting is a mechanic that works until there are animals.
You'll of course be able to build Stone Age units until they become obsolete with Ancient Era counterparts.
There is one thing, you'll get a Band of Homo Sapiens instead of a settler, which is basically a settler with Sentry.
If there is something else, it was unintentional, and should be reported here for me to check.
Also, if you read the initial post, you'll get a pretty good idea what changes are done to the core game. There should not be big surprises.
I'm more than ever looking for feedback now.
