This is a good improvement, there is no way it is overpowered.
As much as I disagreed with you about the DEF of OT, I wholeheartedly agree with you and your reasoning this time
All is very good but... need more expansion in real play to build anything we want to build...
Yep, that's the main problem of this game. Space... I have no place to build anything. And I know my city is not efficient one, but I love some of the old pieces and can't bring myself to demolishing them.
Art Exhibition Kit cost 28k coins and 63 gems, so you need 504 gems for lvl8, ouch, I have 76 gems right now
Start selling SoK
Like I do.
=====
Well, true to be told, I have not seen the new buildings yet. Neither of them. So even if somebody has thousands of gems squared away, it won't be possible to get too many of them in short time.
Actually, IMO, lvl 1 SoK is obsolete. And yes, you can stone me for that blasphemy, but it is true. Virtually all event buildings give more FPs per square than SoK lvl 1, so I don't understand why everyone is aiming getting more of them. I am actually selling them in AD for a while now. SoK and WW and Youth fountain are my main source of gems in AD. If I build all event buildings, I have no space left for SoK. I actually don't have space to build even all event buildings. So I have about 4 SoK in my city and that's all. So if I can get those 4 upgraded to lvl 2, I'd be happy, because then they will be at least useful again. And since I really haven't seen it yet, it might take a while to get 4 upgrades. Under no circumstances I would consider it OP then. (OP would be "mass upgrade" of all of them in single step. Not this, several months or even year long process).
As for the Art Exhibition, the same space concern applies
. Well, after (if) I collect all the upgrade to max, I might replace Maharaja set with it, because I'll get more FPs and goods than the palace in smaller size. I can't add it, there is no place where to. Well, given how long getting all of the upgrades will take I might move forward to another era and gain a few building squares

Question for devs - when is this going to live? Or is it already there?
Thanks
