Uhlan - currently it is broken a bit, I mean
it has a bonus against MELEE. You know what the most advanced MELEE unit is? Longswordsman
Later there are GUN units and I am pretty sure Uhlan should have bonus against them (maybe add something against ranged as well?)
Royal Guard - I have an idea here, which would require a piece of lua. You know, Assyria was first ever really agressive, expansionist empire - the first which started 'capturing capitals'
(Thebes, Jerusalem, Babylon), in the same time it is interesting because managed to come back after fall of Nineveh. I think it could be reflected in ability like this:
'Has bonus when fighting close to capital... Of Assyria OR OTHER CIVILISATIONS!' The second part is reverted 'capital defense'
It would have more flavour and offer more strategy during defense or attack.
Seowon - currently this building is exactly same as the university
(my only idea: because Seowon were creating Korean elites, maybe specialist working in it should give additional production? )
Canals - very nice idea, my only suggestion is to increase merchant point to 2
Roman Market - I don't get what's unique here
Stave Church - well, currently it costs no maintenance and gives +1 faith? In my opinion, a bit more unique and fitting to SC would be: -50% production cost and no maintenance/maybe engineer slot?
Cothon - seaport with 2 additional gold for city connections and 2 additional defense points - I think that's a bit weak, but I have no idea here
Tipi - ...yeah, did you mean that Shoshone will have Tipi improvement from new world deluxe?
Hippodrome - current version is very nice, although maybe it would be possible to put faith bonus here?...
Ger - the concept of Ger is very nice. However, I see that you still have no idea for Unique Building for Huns, and frankly
Huns have no architecture other than tents In my opinion, Ger/Yurt should go to Huns, because
they are all about extremely early rush and they usually have no time for building shrines and barracks - Ger would perfectly suit here. Now appears problem for Mongolian UB
but Mongolian architecture exists
http://goo.gl/W7uidB and also one important fact:
Mongolia shouldn't get Ger because in 3rd component world it would be the only nation which has absolutely no peaceful bonus (even Zulu get Kraal - on the other hand, Huns still have +1 production from pastures bonus, so Mongolia would be really alone pure warmonger). EDIT - what if Shoshone Tipi from the Deluxe could be reskinned and used as Mongol Ger Unique Improvement?
OK. Now we have Viking Longhouse, Agora, Ballcourt, Madrasah and Waag. Longhouse, Agora and Ballcourt seem underpowered for me, Waag is a rip off from Bazaar, Madrasah is nice but a bit bland.
Instead, I have group idea for all these buildings... You see, i
n communitas mod exists lua code which causes 'after building Papermaker you receive X science points', and the same with Greek Agora and culture. Personally I am not very good with lua, but we already have perfect code example, and I think creating UBs with science/faith/gold/culture/golden age points? boost is entirely possible
My ideas:
Waag - netherlands receives gold boost after building each waag - it would perfectly show, you know, financial power of renaissance banks, credits and so on - climatic for Netherlands
Longhouse - denmark receives golden age boost after building longhouse - you know, fame of Vikings expands, more and more people know about victorious conquest! Also, it would perfectly reflect Vikings' peak of power
Agora - greece receives culture boost - hey, where democracy appeared?
Also, Greece has early strong unique units, and it could get more culture during its early conquests (maybe take partonage to deal with city states even better?...)
Madrasah/Ballcourt - they receive science/faith boost (eventually it could be Ballcourt=golden age Madrasah=faith Longhouse=science and this would also fit very nice for gameplay and immersion, with possible exception of scientific longhouse (but hey, all those stories told in the longhouse spread knowledge! Knowledge about new ideas and technologies!)
