If you talk to any hardcore PC fan, one of the things they will eventually tout is the "superiority" of the mouse and keyboard. But there are plenty of gamers who, for various reasons, don't or won't play games on PC unless they're using a controller.
Earlier this week I saw a video of a top 500 Mercy player in the United States, a player who exclusively plays Overwatch on PC with a controller. I imagine it's a familiarity thing: a mouse is easy as buggery to use if you grew up with it, but far less so if the N64, original PlayStation, Xbox et al. was your gaming hub of choice.
There are plenty of couch co-op games on PC, of course, that are built around the controller. Driving games are infinitely better with a controller than a keyboard, for obvious reasons. The one that surprised me was Elite Dangerous: I found it a little more comfortable flying around with an Xbox controller than I did mouse and keyboard. It was probably a matter of not having finely tuned the controls enough, but as someone who loved the pickup and play nature of Freelancer, the work Frontier did for controllers was pretty exceptional.
What games on PC do you play with a controller - and are there any you play that most people would ordinarily use a mouse and keyboard for, like Overwatch? Let us know!
