Souls games.

I really want to like them too, but they seemingly aren't compatible with how I play games. I need to be able to put a game down for a couple of weeks and not feel like I'm back at square one because the specific muscle memory for that game has gone.

Just kinda kills the fun when the game is effectively telling me to get good, when I don't actually have the amount of free time IRL necessary to do that.

The Witcher. I really want to like it. It seems like the kind of game I would love and I recognize that it’s an objectively well made game. However, I’ve bounced off it at least 4 times after getting 1-4 hours in.

Pokemon - having to watch animations and not being able to speed anything up killed my interest

Skyrim - tried a melee run recently and the combat feels like you’re whacking air

The legend of Zelda - played Tears and the story and puzzles were a bit too kid friendly

Doom - I really tried to like it but I felt like I didn’t get anything out of it. It doesn’t scratch that itch I get out of FromSoft’s Souls games where I want to learn a boss’s patterns and die to it a million times.

In general I don’t think I can do story games anymore

Capitalism: I refuse to develop my sociopathy to the level required to participate.

Monster Hunter. Probably tried like 4 of those games since Tri and people keep recommending them to me, saying the newest one will surely be the one to convince me. But I found them all to be a boring grind.

I can think of lots of series that I don't like, just because I'm not into the genre. I think that everyone has genres that they don't like.

I think a more-interesting question is about popular series that I don't like within a genre that I do like.

I didn't like Frostpunk, despite liking city-builders. Felt like the decisions were largely mechanical, didn't involve a lot of analysis and tweaking levers.

I didn't like Sudden Strike 4, despite liking lots of real time tactics games, like Close Combat. It felt really simplified.

I didn't like Pacific Drive, despite liking survival games. It has time limits, and I often dislike time limits in games.

I didn't like Outer Wilds, despite liking a lot of space games. Didn't like the cartoony style, the low-tech vibe, felt like it wasn't respectful of player time.

I didn't like Elden Ring, though I like a number of swords and sorcery games. Just felt simple, repetitive and uninteresting.

EDIT: A couple of honorable mentions that I don't hate, but which were disappointing:

Borderlands. The gunplay can be all right, and the flow of new guns and having to adapt to them is interesting. But every Borderlands game I play, the always-respawning enemies are a turnoff. Feels like the world is immutable. Also don't like the mindless farming of every container with glowing green dots. And for a combat-oriented game, it doesn't make me mix up my tactics much based on whatever I'm facing. While I finish the game, I always wind up feeling like I'm not having nearly as much fun as I should be having.

Choice of Games. I like text-based games, but a lot of games published by this company, even otherwise well-written ones, have adopted a convention of making one win by playing consistently to certain characteristics of a character, so one tries to just figure out at every choice what option will maximize that characteristic. That's extremely uninteresting gameplay, even if the story is nice and the text well-written. I feel like the same authors would have done better just writing choose-your-own-adventure type games if they weren't focused on the stats. I also really dislike the lack of an undo, to the point that I've put some work into a Choicescript-to-Sugarcube converter.

D&D

I've been playing RPG for decades, but play D&D less than once a decade, and my impression goes form awful to not worth my money/time. When I was young and broke, having to buy a player manual + a GM guide + a monster manual when tons of RPG would fit in a single book (Yes I know, clan-books for let's say Vampire are also a money-pit), was out of my budget, then every-time I played D&D, feel like the story were not interesting as concept like alignment and some spells like detect lies would kill many interesting plot. Too which you had a lot of character optimisation often over the long-term (If you didn't take that feat a low level you cannot have the killer feat at high level), let alone the people mixing RPG and miniature games

Sure you can have some funs game with D&D and play it differently but there is so many other game out-there (and so few time) , that why would I even bother joining a D&D game rather than another,

Final fantasy or any jrpg really

Soooooooo long and boring

Name any sports title ( NHL, NFL, NBA, MBA, etcetera )that isn't a zany, over the top SuperTuxKart or Cartoon Network Racing style kart racer and I'm out.

Same goes for any PVP shooter games such as Call of Duty, TF2 Counter Strike, etcetera. Anymore I really find no interest in them because I don't feel like breaking things over some 6 month old who can squad wipe me, all while getting their diaper changed and slinging slurs my way.

GTA. It just seems really boring to me, I dunno. A lot of shoot em up and not so much substance. To be honest I feel like that for a lot of open world games. It may be wide as an ocean but it's deep as a puddle. That's not ALWAYS bad but I generally would prefer a more linearly running game that's a lot deeper.

The Bethesda (and related) RPGs. The core gameplay loop just feels so shallow in both, meaning most of your time is spent wandering with nothing meaningful to do, or in spammy, often janky combat. The parts that are interesting, the character builds and the lore, aren't super involved in most of the game. You spend so little time building characters, and most of the lore is in written logs and books.

Assassin's creed. The movement and combat didn't feel satisfying to me at all

Just about any multiplayer game. I generally don't like playing with randos (why would I want to listen to a 12 yo squeal in my ear that they fucked my mother in a pitch only dogs can hear?), and most of my friends don't play games I'm interested in.

I've failed at getting into any Battle Royale, Survival, or Extraction type game so far.

Fortnite.

Just. No.

Assassin's Creed.

Love the historical gameplay. But I cannot stand being interrupted by the modern day parts. Even if they are small. They feel so disrespectful with my time that I've always been unable to play those games. I forced my way through AC2 but I have never replayed it, despite loving the actual gameplay, just for the modern day boredom.

Dark Souls and any of its copycats. Grinding a boss for hours on end just to learn it's patterns is not how I like to spend my free time. Aside from that: why is that whole genre so bleak? Apart from maybe "Another Crab's Treasure" they're all dark and gray/brown and unrelentingly depressing. Does the gameplay lend itself to that particular aesthetic? Or is everyone just copying Dark Souls that hard?

Final Fantasy. JRPGs just aren't my thing

I think I/we were too old to get into pokemon. I tried 3 games, and got bored about 4 fights in. I'm sure back when that was the peak of gaming, it was amazing. But now after modern games, turn based gameplay is just not for me too

RDR2. Played, but didn’t beat the first one. Some other game pulled me away from it. Tried the sequel and was disappointed by the gunplay.

Pokemon, TCGs in general, Fallout, Darksouls and the related things

Sonic

God Of War

Dark Souls

Call Of Duty

Final Fantasy

Walking simulators
Something like outer wilds should be fine but i get easily annoyed from just running around
Even that i know that in some cases its very fast running around or something

All of them.

About 10 years ago, I was playing BioShock. It was fun, but I kept losing interest. Which was weird, because it was pretty much a game that was made for me - a pretty deep plot, a cool adventurous aesthetic, exploring and discovering different places on the map. I realized I was getting distracted thinking about all the other things I wanted to do - hanging out with my friends, figuring out how to talk to girls, studying so I could get good grades and a good job, learning all about things that interested me, going backpacking and rock climbing - and so I finished the game out of habit, and then set down the controller and didn't pick it back up for a while.

My last game was Red Dead Redemption, which I blasted through in a marathon play-through while spending a month crashing my sister's couch between semesters. My sleep schedule got all fucked, I ate like shit, and I felt like shit. Once I got to the end of the game, I packed up my XBox and put it in a box box. The next semester I sold it to get money to buy climbing gear.

Now I just do the Wordle.

Any of the big popular RPG series. I got through Mass Effect 2 (it was on offer for a quid) but have no desire to go back, and I know that’s one of the more action-based games. I also played Witcher 3 up to Skellig but just can’t bring myself to finish it.
