It's not really gameplay but : not rendering me deaf when launching the game for the first time, games need to have their volume down to 50% by default
I once made this argument to a game dev community on Reddit and was called crazy for it. There are games where I literally have to remove my headsets when they open. Devs that make games for pc should understand that pc users don't just use their pc to play games, but also for other things. So volume control is obviously tied to each individual app/program.
I would like it if all games launched a simplified settings menu first thing after you open them up, before any cutscenes or intros.
Not technically gameplay or genre based, but god I fucking hate games made in Unreal Engine, because they often have a shit-ton of extra post-processing effects going on that you just cannot turn off. There's been a lot of games that I've had to set down forever because the combination of bad FOV and being unable to fix the motion blur/ambient occlusion/film grain(don't get me started) just makes them nauseating to look at for too long.
These are actually two slightly different options. Mouse sensitivity is how far the cursor or camera moves based on how far the mouse moves. More sensitivity means that the camera moves more if you move the mouse the same distance.
Mouse acceleration tracks how fast the mouse moves over that distance and extends the amount the camera or cursor moves if it moves faster or decreases it if it moves slower. In some cases this can feel more natural, but in others it can make it harder to be both fast and precise in your movements, since moving faster can make you overshoot compared to making the same movement more slowly.
Pokemon : make a "I've played this game since RBY, skip tutorial" button
Shooters : MTX in every corner of every menu need to go. I want an option that turns it all off.
Full RPG's : scalable stats option that allow a player to skim class options instead of 900 options per class. So if you want TPG lite it automatically just "levels up" your class for you.
Games in general being over 60gb is an immediate "I ain't installing this shit" - make minimal install package options.
Halo : make an actually coherent story. This one isn't an option or setting....
Fixed/Classic camera for games in the Survival Horror genre.
It used to be the defacto camera style for the whole genre. Then Resident Evil 4 changed into an Action Shooter and sold better, so now the camera style has basically died out in favor of the over used, bland, copying everyone else over-the-shoulder camera.
No settings or options are gonna fix what I find not fun about the genres I don't like (MOBA, Hidden Object, and racing games). I just don't find the gameplay of these genres fun.
