I'll throw in one that wasn't mentioned here yet: Ren'py games are decompilable and give full stacktrace on exception. So, upon encountering something that annoys you greatly (or a bug) in Ren'py game - you can decompile, open the code and edit it.
And, of course, that helps with modding as well.
Hard nope. It might be a fetish for some people, but it switches me off. "Lessons in love" would be an example of that - great game, that is ruined by creepy and psychological horror.
It is mostly taboo/perversion of it. Even the stuff that happens in "normal" porn would be unacceptable for me in real life - e.g. fucking someone else's wife is an unpleasant thought IRL, but is a great trope in porn. Loli stuff is the same, but turned up to 11.
Wrinkles, gray hair and other clear signs of aging are what pushed a woman away from MILF tag. As such - heavy cosmetic maintenance can keep 60+ grannies in MILF category, while lack of said maintenance can push 35-year olds out of it.
I wish for more games where a girl is *eager* to serve/pleasure the man, while rolling down the corruption spiral. Usually that sort of behavior only happens in mind control themed games, not by the will of the characters themselves.
Half a year seems to be a norm - it turns update frequency into "once a year" and people easily recognize it as abandonment.
On the other hand there should be some sort of tagging for increasingly small updates, where game is being stretched for years without an end in sight.
There are two main problems: consistency and lack of personality.
Games require a set of resources and there is mastery in making that set consistent with itself. AI-generated images tend to deviate between each other.
But even with those deviations - AI art tends to be very same-y. Same facial...
That's gonna cost you a lot, while giving dubious benefits. "Visual Novel" = important parts are art ("visual") and writing ("novel").
If you decide to add them - make sure that you game has separate volume slider for "character voices".
It is very limited in QoL features - It falls on the dev to implement good systems for player to interact with the game, and it is common for devs to ignore that.
Achievements work best as a sort of a checklist for completionist, when you can finish the game on your own terms and then go complete them in some sort of NG+.
A lot of free roam games could benefit greatly from being switched to a simple VN. Extra dozen clicks of navigation between scenes rarely improves the game.
Partially clothed>Fully clothed>Nude
Slutwear is best IMO - the kind of clothing that is sexual while fully worn and allows for quick access to all interesting bits.
I found myself consumed by asian webnovels - they are a perfect fit for a relaxed reading. Important trick is to recognize which way writing is trending and abandon bad books before sinking too deep into them.
As for recommendations...
