Take a gander through the comment section of any gaming-related article here on Engadget, and you're all but guaranteed to find at least one person espousing how much better playing games on a PC is compared to doing so on, say, a PlayStation 4 or Xbox One. But just who are those people? Joystiq has spotted a new report from The NPD Group that should shed some light on the situation. Understanding PC Gaming: 2014 calls them "heavy core" gamers. They spend five or more hours each week playing the likes of shooters and strategy titles, and have dropped about twice as much cash on games in the past three months compared to casual gamers. They, perhaps surprisingly, make up the smallest group surveyed: 20 percent compared to casual players' 56 percent, while light core (the same demographic as heavy core, but spends less time gaming on a weekly basis) sits at 24 percent of those 6,225 people questioned.
