Someone please fill me in on how the science-calculation works in Civ VI. Here's my scenario: Island map, Pericles, King. I have 5 cities ATM (around turn 200 on Epic) and am about to jump into the industrial era. I have three campus-districts, all with libraries, two with universities, one currently building a university. I also have the GL, plus I used a GS for that "science per mountain tile"-boost *and* Isaac Newton to boost my university's output. According to the score, I should be ahead in tech, but it seems that Tomyris is leading both me and Vicky (who is also going tall). The reason why this is a bit puzzling is this: Tomyris is going full on ICS (as she usually does) and she's rocking her usual carpet of doom of horsemen. But her cities are all pretty crap. I've just started with spying and *none* of her cities even have a campus - so I can't even attempt to steal tech (the mission isn't even in the list for my spy). Most of them are size 7-8, her largest one is 9. Does the game still generate science simply based on pop, even if you don't own any scientific buildings? The thing is that if you can do without science buildings if you're going super-wide *and* if the absence of scíence buildings/districts makes you immune to tech-stealing... why would anyone try to go tall in VI? AFAIK there are none of the usual penalties to keep ICS under control (like maintenance due to distance from capital from Civ IV or global unhappiness from V). Or am I missing something here? S.
