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.
Bioshock Infinite.
The series of games are great, but this one stood out as something more special imo.
