There's a difference between liking something, and needing it. I'm sure everyone likes being respected, there isn't really a negative to being respected.
I think the problem here lies in people misunderstanding "respect", most likely a whiplash of the whole troglodyte "gangsta!" culture kids these days follow, but respect isn't... A coin, or a rank, nor something you can demand or enforce in any way... If there's something that makes me wanna punt a baby across a mine field is when people start gurgling about "respect" like some sort of currency. "YO BETTA GIMME RESPECT HOMIE!", "respect this", "respect that", etc, etc, etc...
Respect is actually very complex. Respect is something you give or receive free willingly. Only when it's granted in honesty and of free will is it truly respect, and not some fake cover of fear or manipulation. Respect isn't something you can search, isn't something you can try to acquire, it's not something you should try to get, it's something that you CAN receive.
Picture true respect as the most sincere form of flattery. You can't very much walk up to someone and demand they say you look beautiful, or that you're clever, or whatever the fuck really... And you can't go through life expecting someone to walk up to you and say "my god, you're a genius!"... If someone does, great, makes you feel good naturally, but you can't "seek" it, you can't try to "grab" it... If you're so desperately attempting to reach this "respect", then you lack something more important, you lack valuing yourself, for all your good and bad things, and you won't truly be "free" in life till you do.
But back to the point at hand, there's nothing wrong with liking games, and liking them a lot, I sure as hell do, but the kind of people that would label themselves "hardcore gamers", in general, are the same kind of people to whom games are no longer really fun, they're an addiction, like crack or heroine, they are their method of "living", "approval junkies", "addicts of admiration", they're all in it for the "that guy is really good at it!". And as we've established already, that points towards far deeper and graver personality disorders.
L.B. Jeffries: The term "hardcore gamer" has been around long before the 360, or even the original Xbox were even created.
