Classic Game Room. He stopped reviewing nearly as many modern games, which is too bad because his videos were a breath of fresh air back in the day. Also his jokes got old ("Can I play this on the Vectrex!?" was only funny the first few times). He really had no idea how to adapt as Youtube changed.
Apparently the channel is dead now.
Oh god, this is a big one for me too that I forgot about. His review of Pac-Man 2 is the funniest thing ever even to this day, and he had a bunch of funny skits with the Game Com too. CGRUndertow is a fantastic channel too that gave a lot of great recommendations on some eShop stuff. I was really sad when it closed down and was even more upset by how badly it broke Derek to the point he's been in a very upsetting slump.
All while Mark tried to reboot CGR constantly and do stupid things such as make certain parts of a review patreon exclusive, moving them to Amazon Prime, (where it hardly changed in quality and was only done for money, which didn't work out) and instead of asking his YT folks who have been with him for eons there and on patreon for advice, he just flatout killed the YT channel to make it a merch store while disabling likes and comments. Now he's doing this weird 1 minute review system for Tiktok and that's not working either. Considering how badly Derek is burned by this whole situation, I feel that he's also responsible for his current mental state as it doesn't sound like he's made much effort to help him.
For me personally, I don't really unsub from channels unless I get bored of their content or they do something really dumb, but easily the most recent and most hurtful to me was a channel called Toy Bounty Hunters. In 2013 they started a super well-made Power Rangers/Sentai Retrospective that inspired me to make my own retrospective series and it's a really damn impressive passion project. They also made a bunch of PR videos that were fun to watch and whatnot, so I enjoyed their stuff and got into Toku because of them.
But then for some baffling reason, last year they just abruptly went into the far right territory after years of never getting involved with that stuff and always being against hate groups. It started fairly tame with just them talking about the Dante actor from DMC being in DMCV and how much they liked him (since they met him at cons years ago and became a personal friend of his because of that), but then the actor got more open about awful shit like Qanon and far-right nonsense, and I guess because they were friends with him and thought he could do no wrong, they went to any stupid lengths to defend him even as he did more questionable and outright awful things by believing in that group. Then the channel started to go far-right as well, leaning more towards political nonsense and getting mad when Vic got kicked from Funimation. (A giant red flag since there was a damn good reason he got booted)
The second they went and whined about "Game journalists bullying Reuben" in a video when the media called him out on his bad behavior pushing far-right conspiracy theories, I just outright told them in their comment section that I wouldn't be supporting the channel if they continued to push forward on backing people with awful ideas and was very disappointed to see them getting increasingly comfortable with the far right. They responded as politely as they were able since they knew I was a long time fan, but the reply was pretty much "sorry you feel that way, but we support free speech and free opinions." Yeah, because a hyper dangerous fringe conspiracy theory is apparently an "ordinary opinion" despite it causing crazy people to cause chaos at dams and such.
I really wanted to give them the benefit of the doubt and hope it was just because Reuben was their bestie, but then they just dived fully into far-right territory by hosting livestreams with hate group supporters like Yellow Flash and Herohei and making a bunch of comicsgate related videos. I unsubbed the second I saw them whine about Bounding into Comics (a hate group website) getting suspended from Facebook since that just set in stone for me what their new priorites are. I don't think any other tone shift in a channel has made me more sad than with those guys since they went from a super big inspiration for all with their retrospectives to people falling into darkness by backing hate groups. Very sad.
I guess another guy in a similar position I unsubbed from was TheBitBlock since I liked him in 2011 for having good 3DS content and not being afraid to have unpopular takes on games he couldn't get into, (He HATED Xenoblade 1 and was really mad about it getting localized since it was an auto-attack focused, slow paced RPG that I didn't find much fun either) But over the years he grew more and more negative and it got concerning since it went from just unpopular opinions to opinions that were negative for the sake of being negative. Then he lost his mind when he got rejected for Nintendo review copies and was blacklisted for attacking another influencer, and when the Meme Man in office ran for the election he just dove into the far-right harder than anyone I saw. Eventually his content got so toxic and insufferable (he became racist outright and that was the last straw for me) that I unsubbed.
He blocked me on twitter when I called him out for being so toxic that he was cutting ties with former friends and other channels. He's still mad he doesn't have Nintendo review copies and seems to not realize why nobody takes him seriously anymore which is very sad but expected when you act like a total ass and shill for a living meme while also being super duper racist. Thankfully these three channels are the only ones I had to cut off like this so far.
