I was able to download it now. Since I only just started memory segment 5, I guess I'm a little far away from the Battle of Forli but this way, when I get to it, it'll feel like a natural part of the game and not just an add-on, hopefully.
So far, the races can be pretty frustrating, but when you finally beat one (usually takes me at least two or three tries), you do get a nice sense of accomplishment. The assassinations and courier assignments have been fairly easy thus far. I've been trying to hunt for feathers as much as possible but I only have 20 so far. I don't know if I'll be able to find all of them without a FAQ and I don't know if I want to bother. They're basically the same as the flag hunts from the first AC game, except they seem a little easier to find since they seem to always be on rooftops. I wish there was a guide that at least told you how many feathers were left in each town/city.
One thing I'm glad they got rid of from the first AC was the pickpocketing missions. Pickpocketing in the first AC was frustrating and very unfun, probably the worst part of the game IMO. This time pickpocketing is easy even though you don't get much money for it so I don't really see the point.
