Ive never been a 100% kind of guy, especially for these kind of massive open world games. Don't you get bored and ready to move on around 200 hours? I was very happy to finish when I did. Still loved the game, but where do you find the time?
Act 3 was indeed too bloated, and I think the story and momentum suffered a bit too. Some amazing fights though, and loved in the city setting, so not bad by any means.
