have you just never thought that maybe you don't like mechanics that much?
Mechanics are one part of what makes a game. And I'm not even saying that Overwatch is a bad game (though it's definitely not my TYPE of game...I really don't care that much about most completive multiplayer stuff). But c'mon man...best game of all time?
I mean if you want to make the case that it's the best multiplayer shooter of all time, ok, fine. I don't know or care enough about the genre to argue that point. But best GAME, full stop? Let's not get carried away here.
