Oh, don't get me wrong, I have no quarrels with using a gamepad.
Hell, I use it a lot for emulation and other games such as dark souls.
My problem with the whole console spirit though, is that console gamers are objectively casual gamers. They don't want to spend much time getting into a story or learning gameplay mechanics, they just want to pick up the controller and start playing. Sure there still are a number of console games that aren't catered towards these fools, but you can't ignore the fact that console gaming has a massive negative effect on PC gaming. Just look at the graphical improvements we've seen in the past, say, 6 years. They have practically been non existant. The most graphically stunning game to date is a toss up between Crysis and The Witcher 2, which are both how many years old? This is because developers have been developing games for the consoles, who are still using 8 year old hardware, which already was mediocre at the time of release.
So in my honest opinion, which happens to be a fact, if you take gaming seriously, you have to be a PC gamer.
