I see that some people here clearly don't like the thought of a gaming section here at Head-Fi.
But here's how I look at it: the currently-existing forums are ALREADY being "diluted" by gaming talk, if you want to call it that. I see this as an opportunity to move all of that to its own little section, and the audiophile hi-fi traditional music lover folk can discuss their interests in the traditional forums with no distractions. By no means do I expect the main page to bring it up specifically over the main focus on headphones; it's just a little community thing on the side, as just one possible use for headphones.
Also, if you're talking about how there are better places to discuss video games, that is very much the case, but none of those places are nearly as good for discussing the headphones used when playing those games. Believe it or not, people do buy headphones and headsets specifically for gaming (or just want an all-rounder set that also includes music listening, especially given the price tags), and were it not for resources like the big Mad Lust Envy thread, they may not know any better and just go for the "gaming" headsets without evaluating any better options. Better headphones help make games more enjoyable, just as they would make music more enjoyable.
This all stems from the view that Head-Fi is a headphone resource first and foremost, and the uses for those headphones come second.
