I've found this for music genres far more than I have game genres.
For a long time i held a kind of truism along the lines of "If you think you hate something, try it again and you may surprise yourself". This did lead to finding some standout artists in music genres i would otherwise typically avoid from dislike.
Gaming genres however, I've had almost the inverse happen. As i grow older my propensity for try and try again-ing game genres i know that I dislike has greatly diminished.
my own natural game genre tastes are so nebulous and scattershot that i'm not even sure what it is i like specifically in game genres.
to work backward:
I don't really like fighting games. i had played and enjoyed the mortal kombats and tekkens etc from playstation era. thinking about playing those again, seems a positive and nostalgic prospect. booting up mk11 or tekken7 or streetfighter 8 or whatever fills me with dread and disdain. Ergo, i avoid fighting game genre.
I don't really like jrgps. i had played and enjoyed ff7-8-9, perhaps a few other less memorable titles of the era. i would not want to return to actually play those final fantasys but i enjoyed them at the time and can still find some enjoyment engaging in all of the aspects of those games, except for actually playing them myself. grinding whatever to 99 or farming a specific enemy for a specific item sounds like an atrocious value proposition to me now.
I don't really like strategy games, specifically 4x games. I find the high level results of the games explained by passionate players to make for something I can engage with and find interesting. I have installed Stellaris and attempted to get into it a couple of times, but I find the prospect of actually playing a 4x myself to be excruciating. they feel like actual work to me that you need to take a course in to begin to be able to start playing the job.
so what the fuck do i even like?
uh.......
i like morrowind......
rain world, pathologic 2, binding of isaac, noita, elden ring souls games whathaveyou, all the deus ex games even the one you hate, hearthstone(long time ago....)/slaythespire/monster train/deckbuilders etc,
i like no mans sky, postal 2/4, cyberpunk, doom eternal, subnautica, yakuza, caves of qud, the fallouts.
from this haphazard list one can deduce i like primarily first person (but not always) mostly with a heavy narrative focus (but not always) that contain novel interactions in their systems.
i cant exactly give that a genre name but i know it when i see it
i guess my ramblings are to say that gaming genre tags in my experience have not been as useful a category to return to after having judged and made a conclusion on. perhaps even extrapolating to other mediums, would say if you hated horror movies, continually expose yourself to horror movies in the hopes that you see a horror film that you as someone who dislikes the genre enjoys?
then it gets down to the rigidity of genre terms and i'm out i've already rambled enough
