So, is there any reason to play Overwatch then? Yes. And then some. Why? Just for the fun of it. Yes, you read it right: Just for the fun of it!
These days when video games try to be more than they really are, fancying themselves as movies or something else falling in the self-deceiving category of "bigger than life", Blizzard reminds us all why we fell in love with video games in the first place. It's not for elaborate stories, flashy cut scenes or anything of the same ilk. Just for the pure fun and the sheer playability evoking that fun.
Add nothing short of perfect art design and flawless technical execution to the mix and Overwatch becomes the funniest and the most satisfying online shooter you'll ever come by with truckloads of personality and variety.
