Unfortunately, it seems that they have quite a lot of mainstream support. There was a submission on /r/games a few weeks back that was news about future Insomniac games, the source was a post from the ResetEra forums from an Insomniac PR guy. They have support from "journalists" like Klepek and his ilk, a lot of the leftist games studios probably have politics that align with them.
If there's one thing that leftist ideologues are good at it's forming cliques and networking with each other.
The highest point of NeoGAF had actual gamedevs posting. Journos are not part of the game industry, they are part of the blogging industry. They might be covering games this week, and "culture" the next.
The last gamedev I saw posting on ResetEra got screeched at.
Go even further with it, who even gets video game news from Vice and/or Giantbomb anymore? Companies have a a direct line to people interested in their products via tons of social media channels and influencers. The time where companies needed to rely on websites/magazines for coverage are long over - even if they didn't have guys like Klepek ruining their own credibility.
Most companies don't bother sending out review copies to those guys anymore.
Wasn't it the late John Bain/TotalBiscuit who pretty much declared that gaming 'journalists' were being replaced with Let's Players, YouTube reviewers, actual gamers who reach out to the rest of the audience? Any PR guy or blog-tier 'journalist' or 'writer' effectively doesn't count, and the only "mainstream" support ResetEra is getting is from channels and sources that are more aligned to politics instead of games.
And as I mentioned in my last post(I think my last post here?), if you put "politics" and "vidya" at a two-way, the average consumer is going to hit the gas and race towards "vidya".
CrunkLord has it right. What was it, a Beth dev going by Skyrim? Yeah that thread worked out real well for positive publicity and building bridges to the mainstream that matters. An actual verified game dev asking legitimate questions about why the forum is so up in arms about literally everything and having to be the messenger to tell everyone that OTHER developers they know are too put off to even try to become involved with the community because it's so fucking toxic at this point no actual dev wants to touch it.
And what do they do? Do they stop and think "Shit, maybe we need to check ourselves before we wreck ourselves."? Fuck no, they screech at him/her like fucking banshees, respond to legitimate questions and concerns with ire, and walk all over them, a GAME DEVELOPER. THAT'S sure to win them over, huh?
It also doesn't help that they're all too willing to start a fucking crusade against developers/publishers for the mere act of wrongthink/doing something with THEIR game that ResetEra doesn't like, then lie in the face of everyone watching each respective dumpster fire with "Oh we're no doing a witch hunt".
They don't have support. They don't have an actual mainstream. They have a fuckton of ads(that can be bypassed with an adblocker it seems), a 'premium' account service to get rid of those ads so they get more money(while fucking over the advertisers in the process, that surely won't backfire at all), and the dicks of politically like-minded 'writers', 'journalists', and 'insiders' to suck off in desperation to win back the old golden age they once enjoyed and utterly fucking threw away all on their own.
