Photo modes that limit camera movement to within a tiny radius of the player character. FF7 Remake/Rebirth, and FF16, are glaring examples of this.

Or photo modes that fade out NPCs or objects when the camera gets close enough for good screenshots of them.

Just give me a boundless flying camera option and let me live with the unfinished bits if I so choose.

Abuse of quick time events. Some overrated games are horrible about it. I think it should never be used.

3D level design where you can get stuck on elements when you just want to move past them. Especially frustrating in racing games or sections where you have to move fast. Controls are just not precise enough to deal with this under stress.

Visible polygons and interactable polygons are not the same thing. Play Banjo Kazooie and Yookah Laylee (including the remake) to see the difference. The latter has you constantly bump into things because the environment is not smoothed out.

On the other hand some studios take it to the other extreme and make you walk almost on rails, childproofing every corner. A good middle ground is needed.

Games with bird sounds. This wouldn't be too bad if i could turn them down or off but because of this I can't play some games or spend time in specific areas of some games because it make my birds go crazy because they think there's another bird in the house.

I wish we could individually turn up or down all of the different elements if sounds not just music/sfx/voice etc

Games that are artificially limited to 60fps

Not being able to jump in a first person game.

I have two.

1. The Culture

I do not claim to be a 'gamer'. I prefer to be best described as someone who plays games, but not nearly as often as one branded a 'gamer' would play games by. But I've been partly turned off from video games because of the culture surrounding them. The streamers who play games, the RGB droolers, the tech-junkies, the whales, the hype-train types, the multi-hour essay level of delivering an opinion on a game .etc

Not to mention, all of the gamer-branded merchandise from chairs to even drinks. It just turns me off and I do not ever associate with that crowd and it's a damn shame there is so much gullibility with the culture that it is difficult to avoid.

2. Game-Padding

Side-quest after side-quest does a game not make. That kind of thing is what you'd find in an MMO that needs to find things for you to do. Not in a more constrained container of a game that has a fixed story, a fixed completion rate and everything. All it tells me is that the developers did not think of or have had any faith in what they were making.

Gawwdan preventing rebinding is so annoying! Or it's monkey paw wish cousin, letting you rebinding but the on-screen prompts are hard coded to display the default key.

In a simmiliar accessibility vein, I'm hard of hearing so when a game has no option for subtitles then at best I catch 1/3rd of the story.

Wresting control away every time I take ten steps for some stupid exposition. Just leave me the fuck alone. Damn. I want to explore and discover stuff by, you know, playing the game.

This is why Final Fantasy is my favorite game in the series.
