Given the most serene amounts of evidence, which includes the most serene alphabetical achievement list, the most serene indications that Venice as a Venetian city-state has been replaced by Riga, the most serene colors of the unknown civ being taken from the most serene Wikipedia page for the Most Serene Venetian Republic of Venice, and the most serene hint from the most serene previewer that states that the unknown (but undoubtedly serene) "bombshell" civ is most serene indeed, I believe we can at this point assume the Most Serene Venetian Republic of Venice is included in the game in the most serene fashion possible.
I gave him the pieces of evidence, but I guess he ignored it too, oh well.
There is no other European civ that has the amount of evidence that Venice has. Venice is the European civ, there are frankly no other plausible alternatives (though there are a few very unlikely ones).
