Well, for current AAA games, I would agree with you. However, a PC does offer a lot of other types of games that are not on console, as well as the functionality of Windows.
I also just dont feel comfortable with a controller, even if the game does play well with one. DA:I for example, I tried a controller, but eventually went back to kb/mouse.
I still can't use a controller with more than two buttons. Product of my upbringing I guess, I went from an Atari to a NES to PC's.
