JRPGs
I can't think of a genre that appeals to me less. It's like the developers of these games begin by saying "Right, what does Cfrock not like?" and build games around it. I don't consider JRPGs to be RPGs at all because there's no element of creating your own character and 'living' as them. JRPGs give you a set character, with a set name and set personality, who embarks on a set adventure with set outcomes. The most you can do to 'role-play' as them is change their clothes and what type of attacks they do. RPGs, to me, are all about player freedom to be whoever you choose to be, act however you choose to act, embark on the adventures you choose to embark upon, and have the outcomes of those adventures depend on your choices and actions. JRPGs don't offer that. They're just third-person action games, or turn-based action games, that have the wrong name associated with them.
I don't dislike third-person action or turn-based games, though. JRPGs are still bad in my eyes because they heavily indulge in Japanese media tropes, many of which I either simply dislike, others which I actively abhor. To simplify it to the point of losing all sense of meaning, JRPGs are too anime for me to enjoy. With only some exceptions, I really, really, really, dislike Japanese storytelling. I think Japan, as a culture, is pretty bad at telling stories. I think they are too heavy handed with theme, I think they rely on cliché and stereotypes too much, I think their visual media particularly leans on over-stylisation as a crutch far too much, and even goes so far as to standardise the crutches. Think of how nosebleeds indicate sexual attraction in every single anime. It's lazy and makes everything feel the same. I feel Japanese writers, designers, filmmakers, and animators copy and imitate what they like far too much with few creators innovating or sincerely attempting to be original, and the result is a mountain of media that all suffer from the same ground-level problems. It literally ruins games for me. NieR: Automata is excellent in terms of gameplay (well, not 9S), but the sheer weight of the anime-ness was too much for me to bear, made all the worse for how seriously the game takes itself. JRPGs drown in these issues.
JRPGs are role-playing games that don't let you role-play, and they expect you to endure fundamentally bad writing and storytelling, two things RPGs are typically renown for, to boot. I unironically enjoy playing FIFA games more.
