That summary is missing a ton of stuff Stalker:
I'll comment below. Some of this was missed...some of this was not agreed upon.
Barracks buildings scale XP
--Still in debate.
Garden bonus to citrus and wine (not truffles and lakes), possibly oasis
--Missed this, I will update.
Aqueduct - lakes, possibly oasis
--It seems we were kind of going back and forth between aqueducts and gardens for specific bonus, I will go with this one for now.
Mint - no bonus to Gems? (tile left as is), possibly move a merchant slot here from the stock exchange
--Missed the gems, I'll add it in.
Stock Exchange +1g to oil.
--Ddidn't see this in the original debates, don't really see a need for it myself.
Library - upkeep was left the same last I saw. I've seen no proposal to raise it. Statistically it doesn't need to be raised even with a scientist slot moved there. Possibly the slot was to be moved to the observatory instead. This was unsettled as yet.
--I will adjust the upkeep.
Circus - either +1 upkeep or a slight increase in building cost
--Upkeep is already included.
Amphitheater - no bonus to cotton or furs or silk, dyes is fine.
-- I will make the change, still seems pretty weak to me.
Opera House +2-3 with a bonus to silk
--I'll make the change.
Courthouse - I don't know if we have the cost per citizen available. The other stuff is easy enough.
Constable/Police - There was a suggestion a while back to give these a small bonus to yields when the city grows (or enters WLtKD? or both)
--I can say that right the constable is a VERY strong building, -2 unhappy is gold right now. Police Station maybe I could see it.
Hydro Plant could be -1 upkeep and significant cost reduction. (Cost reductions are also a factor here, even if you don't want them to be).
--I will be adding in those cost reductions to the proposal I just haven't gotten there yet. That said...I will warn you ahead of time that I will be fighting any significant adjustments
Recycling center- bonus to aluminum
--Sure
Factory - bonus to coal
--Don't see any need, factories are good.
Caravansary - no bonus to all luxuries, more narrow (truffles, cotton, furs)
--Missed this one, adding it in.
Market - bonus to a couple luxuries (spice, sugar)
--adding it in.
Observatory change was not to remove the mountain requirement but make it within 1-2 tiles of city and grant +2 science on mountains last I saw.
--I'll leave it empty for now, needs a good debate.
I wouldn't mind giving the med lab +1 population
--we can debate more.
Forge was only +1 to iron still (and possibly removed, with that merged on the barracks).
--the removal part definately needs more debate.
Seaport could boost atolls (gold/production?). The sea tile bonus is fine really as it is though.
--I went based on on the last one I saw you and I agreed to.
Also - change Hotels to grant tourism to Natural Wonders instead of boosting it from culture.
--Ah hotels and airports...I knew I missed something! Also...hotels boosting natural wonders is fine...that without the culture would make them much weaker.
Possibly add Wind Plant as a non-fresh water coastal building boosting coasts or isles/work boats.
--Why? Coastal cities are great right now.
