This might be work in progress. I am pretty sure about No 1 though.
I still mean to play Assassin's Creed IV: Black Flag (I like AC and boats, and that time period) at some point, but man there are too many games. I essentially still have a lot of 2011/2012 games I really want to play. The Last of Us is probably good too, but I only have so much time.
Essentially Crusader Kings II should also be on this list. They released a buch of expansions and really see games as a service. Probably betwen Bioshock and BF.
BIGGEST FUCKING DISAPPOINTMENT IN GAMING OF THE DECADE
