This is kind of a tough one, because the Blizzard thing is obviously shocking and horrible, but I feel like it's just gonna become standard business practice going forward. People are gonna be putting Crimea in Russia, pretending the Armenian genocide never happened, and of course, capitulating to China. Rainbow 6: Siege had a moment in 2018 where they removed images of skulls and slot machines from various maps to appease China
before reversing course. Blizz also skates because a lot of big companies flinched and gave into China at various points. It feels a lot less shocking than the NBA mishandling their China stance.
Anthem was a monumental flop, but again, those happen all the time.
In both cases, Acti-Blizz/EA are somewhat insulated from these isolated, bad decisions through their massive portfolios.
THQ Nordic being a smaller company, definitely "feels" their controversy more. Not only that, but 8chan was so bad they literally got wiped off the internet for (checks notes) hosting multiple instances of home-grown terrorist materials. People like to talk about how bad FB, Twitter, YT, and Reddit are, but no one's gonna fault someone for doing an event on one of those platforms and some shooter livestream/liveblogging on those services. They're just too big tent. THQ had their pick of smaller sites to try and do a more unconventional AMA, Remedy did their research and chose Era as a platform. I dunno, THQ going to 8chan was always more downside than upside. Literally worse than 4chan. If they went on 4chan, that wouldn't have been as bad. Yikes.
Even though it's counter-intuitive for an award like this, I do get tired of seeing EA and their ilk on the tops of lists all the time, it feels important to "recognise" smaller companies for "awards."
Looking back ten years from now, seeing "EA made a bad game" isn't that interesting. Seeing "THQ Nordic does AMA on 8chan," is interesting, because ten years from now young people are probably saying, "wait, what's 8chan" if not "what's an AMA," and possibly, "what's THQ Nordic?" So for historical context, having such an unusual event as the Gaming FotY is something I'd like to see.
1: THQ Nordic's AMA on 8chan
2: Blizzard's China eSports scandal
3: Anthem
I feel like there are probably 50 other "fails" that had to do with streamers and/or the FGC.
edit: not even going to count Stadia, because Alphabet/Google seems to operate on a principle of most of their projects failing if it allows them to have a few hits.
