Female MC period, bad art, bad English (unless intentional to denote say, a Slavic character), unoptimized sandbox (by which I mean clunky map, or little explanation of how to navigate such as places you can click not really highlighting or being obvious), RPGM (it has bad art during anything that isn't a CG, and I cant stand the RPG-like sections/open world), almost no NSFW (I'm fine with a slow burn when it comes to important characters, but if you're going an entire update with no more than a nipslip or something similar, you're doing something wrong), NTR that's either unavoidable or "skippable" (it happens but you don't see it), ideally it wouldn't be in games at all, but if it's at least something you can obviously and easily prevent (or able to be turned off entirely at game start) I'll at least give the rest of the game a try, but in the same vein when a dev constantly has other asshole dudes swooping in at the girls, that you then have to beat off (with your fists, in a fighting context), even if its guaranteed never to end badly, like, I just want to deal with hot babes, I don't need antagonists too. stupid grind (i.e. do the same thing 5 times ESPECIALLY if locked to times or days of the week, only to get one step of progress on a LI), Japanese 2DCG (the art isn't bad persay, but I just cant stand it), scat, gore, Futa/Trans/Trap LIs or fuckable characters unless they're completely avoidable (and very obvious what they are so you aren't just suddenly surprised with a dong, its unpleasant), real porn, incompetent writing (while I get not every dev is a Pulitzer prize winning author, there is a bar they shouldn't be going under), updates that take genuinely a year+, I understand things take time, but even if it results in smaller updates, I'd prefer every few months (or every 6 or so) rather than waiting a whole year and forgetting about the game, and finally (at least off the top of my head) games that either get rid of love interests (looking at you acting lessons), or force you to pick and choose, i.e. if you pick one girl, you're locked out of another, or punished for dating several (if I like the girls, give me all of them please and thank you). Of course, that's just the ones I'm able to come up with right now, I'm sure there's more, I'm quite picky sometimes.
