I finally transitioned to the Roman era! Plantsims really do make generations quicker. I downloaded Midge/ Velco's mods too including fairy and mermaid mods to make supernaturalism more interesting. I don't have any mermaids yet (and maybe won't since the way to get them in game is to teach them the sea shanty, which requires them going on vacation with the oceanography mod), but I have my first fairy!

I'm letting them have pets/ greet strays so werewolves are possible. I assume I can't get vampires, witches/ warlocks during this challenge due to the lack of greeting allowed with non-challenge sims. I might be able to have aliens down the line but no telescopes during Roman era.
