I'm strongly against Venice as a civ, it's perfectly represented by being a city state, why does it need to be elevated to a whole civilization? here are other countries that I would much prefer to be included, even other european countries such as Hungary or even the Holy Roman Empire again. Venice is a place you go to visit only, and doesn't belong competing with civs like America, Zulu, Siam, Indonesia, Sweden and so on and so forth. They types of interaction you would engage in with Venice simply didn't happen in any considerable capability in the real world. They were never feared or conquered or anything of the sort, it would be more immersion breaking than the mythical natural wonders, as those at least had a believable effect on the real world.
