Devs who are not transparent about tags, and future content.
I said it before, lots of problems would be avoided here if devs was not being vague all the time.
Not saying they have to spoil their story, etc. No one is asking of that. But a good layout of tags that can be controversial would be nice.
Any forms of NTR. Yes, that includes LESBIAN NTR.
Speaking of lesbian.. I hate lesbain just being thrown in just to have it.. Like shit be coming out of nowhere I swear. Not only that,
I cannot stand it being forced either. Like I don't hate lesbian at all.. I even find it hot depending on how it's executed. Aka MC's involvement and if they are doing it to please the mc. But man, badly executed lesbian content is a plague in my opinion. (mostly talking about harem in this aspect.)
Sex scenes without MC. (Sorry not a fan of being s SPECTATOR when I play novels. I prefer to be in the action.)
Sandbox.. Like EWWW.. I still believe sandbox is legit aids and do not belong in VISUAL NOVELS.
RPG... Not even going to say why, it's obvious.
TMI (To much information) Don't need to know how many dicks you sucked, fucked, in your lifetime.. Don't need to hear you entire catalog of bodies. Worst thing is when you fucking and she start blurting out all the dicks she had.. certified BONER KILLER.
PUSSY MCs... Like man why can't it ever be normal main characters? They always gotta be the biggest pussies ever man.. It's legit unbearable dawg. Not saying they gotta be some "alpha" but dude have a spine for fuck sake and stand up for yourself. The bullied MC trope is overdone too.
Annoying ass male "best friends" in novels.. Like dawg this by far is as worst as NTR to me.. Like dude I can't name many games where a best friend don't make you want to drown them. They either super pervy and annoying praying on MC's family.. Or just downright unbearable to deal with. Imo the only "best friend" I will accept is if he's their to be CUCKED only by mc.
And that's about it. I can go on and on, but I will never stop talking so I just listed my MAIN ick when it comes to novels.
