If we talk about the last decade. we need to remember that the PS4 and Xbox One only released in 2013/2014, so games that were released on the PS3 and Xbox 360 surely should also receive an honourable mention.
When I look back at the PS3 days, then Hitman: Absolution and Assassin's Creed: Black Flag as well as GTA V also deserves a nomination from my side.
But this is such a vast concept, as people don't play the same games/genres. I for one can't play FPS games, and have never really been a fan of a game with a magic connotation connected to it or that has beasts/demons/monsters in the game.
So my choice of games has usually been sports games, sim games like Civilization and Simcity, and 3rd person games without mysticism like GTA and RDR.
Also Zombies/horror games have never really drawn me into buying it, even though I love the movies/tv series.
