I think I am going to go with
Babylonians-Romans-English-Dutch

Definitely going with:
 Olmecs -> Mayans -> Khmer -> Dutch

I think it depends on the map. Starting location with mountains would mean Zhou, with rivers Harappans, coast/mountains Olmecs. But Babylon and Egypt look like a fairly good choice that is independent of map. After that I like Persians, but Rome and Mayans also interesting. For medieval the Franks and Khmer, Teutons or Umayyads seem pretty strong. Depends on the situation of religion for me, but Khmer and Franks probably safe choices. For early modern I don't think we have seen all the unit stats and traits, which makes this difficult as of now. Edo Japan, Spain, Joseon, Mughals and maybe Ming look attractive to me. So possibly a few choices: Zhou > Mayans > Teutons > Mughals would be interesting.

I'm definitely picking Joseon only to be able to see the glimpse of Industrial Era technologies and unites (as long as they are not intentionally disabled for Lucy OpenDev). Especially an artillery unit.

I will go for whatever supports expansion, to begin with, and after that decide what to do depending on the map and how the AI reacts towards me. 

I have 2 playthroughs already set up :

1 - Roleplaying a pre-Mexican country : Olmecs > Mayas > Aztecs > Spanish.

2 - Naval run : Phoenicians > Celts > Norsemen > either Dutch or Joseon (which would also presumably allow researching Industrial Era technologies).

I also want to test a full random run.

I would absolutly love a random mode at every era. Did Amplitude confirmed this feature ?

That would be very interesting especially if they randomized research and civics 

Made a post about this Olmec > Mayan > Norse > Joseon

I picked Harappans then Franks in medeival era, I got 100% pop groth (1 pop/turn)
