for me: 1. low effort design/animations, why does everybody have the same body/face structure? this just kills the mood, and makes you wanting to not waste your time trying to invest in the next character, they are all the same anyway.
2. Games that doesn't have a in game guide or something. "oh shit where i am going now, what quests i got right now", this is something that happens a lot in adult games at least with me, and I don't want to open a Walkthrough to know what quests i have, so could you please put a button that easily tell what quests i got and say a tip of what do i need to do next? is it that hard? Goodbye Eternity made the quest mechanics really well.
Overall, Goodbye Eternity IS a really good game, with really high quality graphics/animations with not so forced relationships.
3. Why is every female MC so dumb, completely useless or so innocent in these games? I know that corruption is a fetish and all, but corrupting a well written MC/female character is 100% better/more exciting than corrupting a really dumb one.
The main character from The Magic Town literally let her body be possessed by a ghost and she (mc) is so useless (words from the own game) that her body literally throws her spirit away because the ghost is using it better.
Besides that, my god, someone with 16+ years should know what someone asking for them sitting on their lap means.
I am sorry but I don't want to play with such dumb and useless MC, specially if comedy isn't the main focus of your game.
4. Excessive grinding. Why? I do understand some grinding to make combat easier, but grinding EVERYTHING? really?
5. why is every girl lesbian or bi? I know that opens some new scenes, but you could make it different than "she just like pussy and dicks" Ypu easily could put a drinking/mind controll/drugs to forced them into the lesbian/bi path, but why bother, just make her lesbian anyway.
One game that I really like called Another Chance committed this mistake, almost every single girl is lesbian, and I mean lesbian because some of them makes no sense at all why are they having sex with a dude.
A new character appears and she makes something that reveals she is lesbian: yeah, of course she is.
It just breaks immersion, lesbians doesn't like guys.
6. make the game have consequences, if you are with someone, and they don't appear to be the type who wouldn't mind you going out with other girls, make that if you do betray them, they will not want anything to you anymore. life is made of action and consequences, and a game should have that too.
Or at least make really clear at the beginning to all new possible characters relationships that the MC won't stick with just one, so it doesn't feel THAT much unrealistic.
It's so weird to me when a character that looks like it wants a monogamous relationship randomly decides to have a threesome.
