Yeah it was being able to wildly change your civ in Humankind that I found jarring, from the dev Q&A it did sound like they were going for a much more logical progression, like Phoenicians into Carthaginians for example, rather than Rome into the USAYeah, I think it depends on how natural it feels. If I can play "Vikings"->Normans->France then that will feel like a natural progression, as would "Vikings"->Normans->Britain or "Vikings"->"Medieval Sweden"->Denmark but if it's "Vikings"->China->USA then it's going to feel arbitrary. There seems to be an unlock system controlling your exits from each age which will hopefully ensure that it does, we shall see.
