Not sure how far exactly I got with this one, but I think I’m about half way to the end. As far as I can tell, I have completely upgraded my mansion, so money is really no longer an issue. I’ve also been gathering various bonus items, but I feel there are far too many and I’m not motivated enough to collect them all. If I can remember correctly, I have allied with the thieves in Venice and killed one of the local leaders. It has been a while, so I cannot really remember if I got further than that.
