To me this would be Far Cry 4, I was a huge fan of FC3 and FC4 with the coop mode got me interested more than I was expecting!
There are a lot of games I also played and liked, not necessarily in order of appreciation:
- DriveClub (still playing this one)
- The Last of Us:RE
- Thomb Raider:DE
- Infamous:First Light (I prefer it over the main game, it feels a bit faster)
- Metal Gear: whatever they called it
Music really goes to Metal Gear, I loved the sound in this game!
Graphics will have to go to Infamous:SS, this is just unbelievable how good this game looks at times... DriveClub is pretty amazing too...
