I think we all know what Overwatch is; a stylised team-based shooter from Blizzard. And we all know that it's pretty much unrivalled in the genre.
2016 was looking to be the year of the "hero-shooters," what with Battleborn, Paragon, and Overwatch duking it out for the crown. Now, at the start of 2017, I think we can all safely say that Overwatch wiped the floor with its competitors.
Featuring fantastic characters, slick visuals, and an addictive one-more-match mentality, Overwatch set itself apart from the other hero-shooters. Sure those games tried the same thing but they lacked that special Blizzard-level of polish and swagger. Overwatch is as good as it gets right now on the competitive multiplayer scene, and was voted game of the year by many an outlet.
