Here is a save if anyone is interested. I started random civ, emperor dif, standard size, standard pace, continents and this was my only game save the whole time. I got spain, never really was able to settle near a natural wonder (thought about capping m'baza congo just for the barrier reef but never got around to it), missed a couple wonders I wanted like Notre Dame, but went on to win a pretty easy science victory.
Venice's status at this point, since I liberated him, has grown to size 9 puppet of himself, as he remained the entire game.
edit: I just noticed something. The galleass south of Barcelona has Great Lighthouse bonus, but I don't own Great Lighthouse. Venice has it. Is the promotion supposed to stay on the unit even though I no longer have Great Lighthouse?
