Completed on 95%, did not collect all feathers, did not find all statues.
Loved the game for the most part, but seems like developers got a bit lazy and the game became both boring and unreasonable in the end storywise. I just couldn't get more frustrated at what happened to Ezio and what he did. Also, throwing armies of people is just as a lazy way to signify the game ending as in the first game.
The enemy AI is a bit janky and annoying, and the overall game design is just unpolished.
I loved the atmosphere of the game, its game mechanics, enjoyed some parts of the story, but it is not as great of a game as I expected it to be.
