The changes look awesome.
On a side note, I noticed a bug with Burmese UB (Paya). It should replace scriptorium but it doesn't. I checked PAYA_CIV4BuildingInfos.xml and it seems ok. Maybe there is an entry in some other XML that should be updated?
And, doesn't +15%
give a little bit too much (for such an early building)? I could be mistaken, maybe it's balanced because it goes obsolete "quickly"?
In my humble opinion, +%
(not just Paya, but some others as well (Plunder for Goths comes to mind)) should be replaced with one of the following:
- +
- +
if connected to capital
- +
for each connected city (max: <insert number>)
As for Plunder (Gothic UB that replaces Jail), I'd even remove any of suggested and put this insted:
Increase Pillage gold or, this may be far fetched, any unit (or just cavalry) trained in city with Plunder UB gets Pillage promotion
