Example, I believe Assassins Creed Black Flag is the best in the series instead of AC2. It has awesome progression, exploration, naval combat and stealth. Assassins Creed 2 was good, and it was my second game I played in the series but I never got as attached to is as 2.
HALO REACH most of people say it HALO 3 but for me the story of Noble team was the best
