Most gamers from my experience that refer to themselves as "hardcore" gamers are male teens or 20 somethings that don't blink an eye at spending three or four hours a night playing Call of Duty most nights of the week online. They barely touch more than two or three mainstream series and spend hundreds of hours playing the same games online during the course of the year until the next round of annual updates appear.
When you go to a place like here where people love a wide variety of genres, have interests spanning many generations of gaming, and appreciate niches like import gaming and modern vertical and horizontal shooters, those are the truly dedicated fans of this industry as I see it. And almost as a rule, we all shy away from that term since we don't like what it equates to. And I also suspect that many of us think it has a bit of an immature ring to it.
And GameFaqs is a vast wasteland where their forums are concerned. Go look at something like many of the Atari 2600 forums. Thousands upon thousands of postings yet none have anything to do with the topic at hand. I require at least a basic level of proper moderation in order to participate at a forum. That simply isn't present there and the results of it show.
If I'm using that site, it's to look up things like cheats, release dates, and rely on their database of software released for each platform. GameFaqs has its place but it sure as heck isn't to participate in their strange collection of forum communities.
