Honestly, at this point I am all for introducing a rule - in the next elimination thread - limiting amount of times one person can downvote one thing, I'm thinking of setting that limit to 3 or 4. On one hand a participant should be free, but on another it is natural reaction that the majority of group of people are annoyed when something's position in the ranking is disproportionally influenced by one person, and the problem is unavoidable in a system of +1 upvote -3 downvote and relatively few people participating here (dozens, not hundreds).
The limit could end when only few civs remained, so a participant couldn't be locked out of particiation.
Don't write people are annoyed with someone's behaviour, because you may be edited for possible trolling/
Anyway
Going back to an issue discussed earlier, that UI<UB<UD
I totally disagree. it is very situational, but I think UI are the top of it, because all civs can build base version of a building and district, but cannot build the base version of UI (unless it is Stepwell).
Half price district is nice, but other civs still can build this. And if you have very early unique imrovement with production and/or housing bonus (Terrace farm,
oh no... Mekewap again) you will probably notice very little difference in construction time.
Examples
Cree. This is just slightly below average civ without Mekewaps. But mekewap rises them to one of the best sci civs, very competent in domination and in my opinion the very best civ for playing tall or wide&tall (edit, sorry, second, i forgot about Kongo). mekewap completely change the tier Cree belong to. Are mekewaps available to others? No. The closest would be hybryd of outbackstation, maali mine and stepwell. Noone gets it
Australia. Bonus hammers from unlocking UI come later than Mekewap upgrade, but because of outback station you don't build many mines, so no decrease in appeal = Australia benefits from its unique ability. If there were no outback stations, Australian unique ability simply is greatly weakened. Huge impact on Aus.
Indonesia. Already has strong abilities and unique unit, working perfectly together, but without Kampung city cannot grow/produce anything in resonable time. kampung has decisive role in growing indonesian empire. Can any other civ get it? No.
Sweden. This case is the most absurd for me. In unique ability thread, Kristina was upvoted highly and finished IMO highly overrated, even though any civ can get her bonus with proper micromanagement/ AI trading. And here we have Open museum close to eliminate very early, and I ask why. Its tourism output is slightly less than themed museum. But hey. Everyone can get themed museum, noone can get OpenAir museum (ok, Canada can sth less strong but similar). To get 1 museum themed you have to construct district+amfitheater+museum and get either archeologist or great person. To get SEVERAL open-air museum you need to construct one builder. It comes lateer than districts' museums, but once you get them, you spam them faster than aquiring great works. The difference between Kristina's final position and probable open-air museum position is a clear absurd to me. I am not a fan of Sweden in civ6, I played only once, so may be wrong)
Macedon. Everyone can get barracks, but what I rate is ONLY the unique ability of the building. And it is freaking awesome. Macedon without is is high one the list of scientific civs. But with Basilikoi Paides Macedon becomes the ultimate number1 science civ and probably the most broken in civ franchise history. (maybe not, civ4 Inca rules)
More exmaples: Acropolis and so on. Obvious case. It defines the Greek strategy.
And so on
And the opposite.
Rome. It is half priced, but if Baths don't exist, Rome still will be able to construct Aqueduct. So the bonus aqueduct gives to IZ is not a factor for me, half price is a little factor, just work more mines, get military engineer. And what if Rome would have not baths? They lose 2 housing and 1 ammenity to support this housings (oh, have I ever mentioned 2 housing is a part of bonus of 1 earlygame Mekewap?
oh no... Mekewap again). Is this that impactful on Rome strategy? IMO not at all. Does it change the tier Rome belongs to? Not at all.
2. Arabia - Madrasa [20]
3. Australia - Outback Station [24]
8. Cree - Mekewap [15]
10. Egypt - Sphinx [6]
11. England - Royal Navy Dockyard [19]
14. Germany - Hansa [28]
15. Greece - Acropolis [28]
18. Inca - Terrace Farm [26]
20. Indonesia - Kampung [25]
22. Khmer - Prasat [13]
24. Korea - Seowon [15]
25. Macedon - Basilikoi Paides [21]
26. Mali - Suguba [26]
27. Maori - Marae [26]
29. Mapuche - Chemamull [13]
34. Persia - Pairidaeza [27]
35. Phoenicia - Cothon [26]
36. Poland - Sukiennice [10]
37. Rome - Bath [16] 1
9-3 explained above, doesn't have big impact on Roman strategy. I defended trajan as long as it was possible, but this part of Roman set is of very little impact
38. Russia - Lavra [31]
41. Spain - Mission [16]
42. Sumeria - Ziggurat [26]
43. Sweden - Open-Air Museum [3]
2+1 explained above. Absurd to be eliminated so early compare to Kristina's unique ability
UPDATE
someone is 8 times in a row downvoting the same. But I must apologise and admit it is not behaviour against community, thread idea and is not causing annoyance among many people here, and definitely is not trolling, because trrolling is understood as using proper name for certain things. Otherwise I would be edited. Maybe my last post here, as I have been already edited twice
