ok, so for Venice, how about:
1) Control, Constantinople, Dalmatia coast, and have a city in Greece, Cyprus, Crete and Rhodes by..... 1450 should be fair.
-Wow thats a really long UHV!
-The purpose of this UHV is obviously, historical accuracy, and for Venice to establish a naval trade monopoly around certain parts of the Mediterranean.
-by 1450 or in 1450?
2) Control 10 luxury resources and build the St Marco Basilica by... 1570
-Main purpose of this UHV to encourage Venice to build both the Marco Polo Embassy, and St Marco Basilica, both which are "historically" in Venice
-Number of resources required increased from 8 to 10 as its rather easy for Venice to get luxury resources once they get the islands required for the first UHV
-Venice in real life history is also key to the trade of many luxury resources
-by 1570 or in 1570?
3) NOT DECIDED YET! I still think "get X gold by Y date" UHV will be good, but i heard a lot of people are against that, though im still not sure why. I of course will like to hear suggestions for Venice's 3rd UHV, but i will appreciate it if you give reasons as to why you think this certain UHV you thought of will make a good 3rd UHV.
Usually, not all the time, but usually the 3rd UHV is the one which the civ never really accomplished in real life, but would definitely have done it had certain factors gone their way. I will also appreciate it if this 3rd UHV makes the Venice we see in the game more "Venice-like", if you know what i mean.
