There are only two types of people that game exclusively on PC.
1. The early 20's douchebag who only plays AAA multiplats, and knows nothing about video games because he is too young. He's too shallow to try out any game made before he turned 16, and will forever be a clueless idiot. In addition to this he usually has godawful taste in games, proclaiming mediocre nonsense like Payday, to be a "good" game.
2. The early 30's douchebag who has a wife, kids, and a career. He used to play fun games on other systems, but has long lost touch with the rest of the gaming community. He only gets to play about five to ten hours a week, thanks to his shitty workaholic lifestyle. He thinks he needs a $300,000 house, a brand new SUV, and a PC that costs over $2000. His wife is a fat ugly hog, and he isn't much better. He too only plays AAA multiplats, and has no clue about most of the gaming industry.
Both types of people ironically refer to themselves as "Master Race", despite being a piss poor excuse of a gamer.
Both types of people are amazed by graphics improvements that move at a snails pace compared to yesteryear.
Both types of people spend more time on internet forums than they do actually playing games.
