A "scene" can be quite cancerous. There's so many negative factors to deal with with gaming that it can burn some people out. There's elitists, fanboys, scalpers, and general negativity out there.
I always say "You do you" but I also scratch my head on some things that just don't make sense. Paying someone roughly $300 to CPU upgrade an og xbox so xbmc will work a bit better but it doesn't help games or anything? The concept is cool at a diy aspect under $50, but a Kodi setup that's cheaper and better exists. $600 on a dream C64 setup? Ok, I don't have any desire to play C64 but if the build makes sense and makes you happy, cool.
There's a lot of "my biased opinion is fact" types that'll ruin any intelligent gaming discussion as well, so I completely understand why some people won't go near a scene
