(In no particular order)
1) Gacha games of all kinds. I can see I'm not alone here. Good. These "games" are wretched cringe, and I am disappointed in humanity. Guys, please have more self control (and self-respect).
2) Resident Evil 4-9,999. That's right, the whole franchise after 3. The series lost all restraint, stepped away from grounded east-meets-west body horror, and transformed into schlocky garbage. It has never recovered.
3) Live service games of any kind, but in particular "games" like Helldivers.
4) Call of Duty. Man, I used to love the series back in the 360 era, I'm not going to lie. But now look at it. What the hell is even that? I never want to meet a single person who the games' aesthetic was designed to appeal to.
5) nuDoom. They're trying to pass the Doomguy off as "Doom Slayer." Doom. Slayer. The 2016 reboot arc is a hard thing to watch, with its Diablo III-styled "demons" and embarrassing presentation. As much as some fans want to whine about it, the simple truth is Doom III was more true to the Doom franchise than everything post 2016. The newer games are more Serious Sam in gameplay (which itself isn't a bad thing... I guess), but that's not what I dislike the most. It's everything else.
6) Sony's "Hollywood" games. Gag me with a spoon, man. The PS4 era was lousy with 'em, but to a point so was the PS3. Heavy Rain, Uncharted, The Last of Us. Thankfully, by the PS5, Sony basically ran out of money (and studios), and we were spared any more of this tripe, but the Druckmann deluge was just depressing to live through. Detestable, low-rent "film-makers" trying to give their awful "visions" a place to stand in the videogames space. Eww.
7) Anything Rockstar. People eat this shit up, and Rockstar makes bank. It makes me sad. Everything they do is misanthropic, mean-spirited filth (and yes, I use the word like a true puritan). This is one of those rare instances I agree with the crazy attention-grabbing lawyer. Jack Thompson was right: GTA is a terrible franchise, and it's had a terrible effect on the games industry. I'm upset to think that millions of kids are exposed to this trash, and it brings me to wonder if the general regression of societal values doesn't in some way go hand-in-hand with the mass-consumption of this insidious, hateful franchise. That's an unpopular opinion to be sure, but there it is.
8) Destiny. Though I'm starting to feel that people don't love this game as much as gaming-related news sites want you to believe (they have to write about something after all). I just do not get the appeal.
9) Ubisoft's games are basically one big franchise, because they're all largely the same. And I hate them all. But I think at this point, Ubisoft fatigue is high enough that this is probably a moot entry. But I hated them before hating them was cool. I was sick of their crap around the time they squeezed Far Cry 3 out over a newspaper. The same contrived, goofy setups, the same cut-and-paste gameplay, and sometimes between entries, the same friggin' map!
10) Borderlands is an easy thing to hate on, but again, I'm starting to wonder if listing it is redundant. I get the feeling that people are collectively getting sick of it by now, too. I liked the first one well enough, as janky as it was, but man, did 2 ever grind my gears. That game's writing and presentation was basically a psychic assault upon the player. I get that some people find it to their liking. I do not like those people.
11) Fortnite. Yeah, I thought that one goes without saying. I don't think it's a game for people who actually like videogames.
12) Anything first-party. The big-three are so out of touch it's hilarious. Nintendo's "ah-ah-wah-oh-oh" stale corporate flavor, Microsoft's icky wokeisms, and Sony's... well, nothing. This generation and the one immediately preceding it produced some of the worst first-party slop I've ever seen.
13) Elden Ring. The game looks like piss and plays like shit. A big, empty, and thoroughly ugly world with nothing interesting to find in it but rehashes of recycled DS3 content.
14) Boss rush games. Games where everything is either a thinly-veiled (or sometimes just in-your-face) excuse to throw "boss fights" at you. Because level design and interesting regular encounters take work, and today's developers are lazy beyond measure.
15) Faux-retro games. Games made by people who really don't get the point, who think what made old games great is how ugly they were. For a while it was games with MS Paint "pixel art." Now it's low-effort "OMG jumpscares just like Silent Hill" "horror" "games" with "PS1 graphics." I hate them all (with a few scarce exceptions).
15.2) Anything Remedy post Max Payne. Boy, did they ever lose the plot. Meaningless drivel.
