100% this.Problem is...
Many people want to make a living out of making a porn videogame and that's all, that's the whole plan.
No vision, no planning, no target audience, no long term ideas...
So they make a porn game to a lot of different audiences until they find their niche and finally works.
But by that moment, the game is already a couple of years old, and left thousands of players disappointed.
This is the primary reason to porn games getting canceled/abandoned so early.
Imagine going to the kitchen and starting cooking... something, nothing specific, just a bunch of ingredients mashed together and boiled or friend... at the end you get a mess that nobody wants to eat, but some will feel bad because they really were expecting something cool and saw some potential during the first 5 minutes.
I seea lot of porn games thatstart making the game withouthaving any kind of rought draft of what they want to do with the story or what they want the game to be andlet polls decide the order of everything, wich ends up being a mess.
Not even an abandoned game but Monster girl 1000 is a good example of this. THe game started wanting to make something like Monster girl quest, then suddenly at one point they swapped to using maps and being able to move, then they abandoned the idea inmediatly after. It also has several plot points in the story that amount to nothing because they introduced them without having the entirestory fleshed out and probably forgot about them. To put an example is like by the end of this game the "potion"from Lisa has nothing to do with anything in the story despite the game heavily hinting it is the catalyst that makes the game start.
