Well as my testimony i grew up on a mixture of PC gaming and consoles, starting with an acorn and sega mega drive.
Teen years i played predominately PC games, though the irony is i rarely if ever actually purchased games because they were so easy to download, crack and play for free. Not proud of it, but thats how it was.
Now, the only games i play on the PC are free to download or platform specfic. Even though i knew going into it Dragon Age played better on the PC i bought it on my xbox. The Mass Effect games look stunning on a PC render, i played them on the xbox.
Why?
PC Gaming requires being sequestered away from society in a room, by yourself, probably with the lights off. Hunched up to a computer monitor with a mouse and keyboard is less comfortable than crashing on the sofa with a game pad and 46 inch TV. If i completed a marathon play through of dragon age on the PC, i would have zero interactions with my other half the entire day. Playing on the xbox, in the lounge, she can come and go, watch, dont watch, be a part of the experience, and ultimately, kick me off when is reasonable so she/we can get use of the lounge TV
So for me, it all comes down to the social practicality. PC Gaming implies a greater degree of isolation
