To keep the first stage of the game from being too complex, I’ve kept it linear. As I mentioned before, any ACCEPTED QUEST must be completed if it’s not, they will receive a penalty. This means that in future quests, if an unexpected element arises, they’ll have to endure it in order to avoid punishment (this part going to be sharing, at least thats what Im thinking right now).
So for players who are not interested in "other guys dick" sharing / ntr / Whatever you want to call other males having sex with a LI. The way that they can avoid this is my NOT accepting certain quests?
If this is true, I would recommend that you make it clear WHICH quests will lead to "other guys dick" content. It will probably annoy players who don't like that kind of content if they have to constantly re-load.
Also, do you have an estimate of how much content will be "other guys dick" content? Is it 25% of the game? 50%? 75%?
This is something I would let potential players/$upporters know up front. How much of the game will they miss if they don't like the sharing elements?
However, they can also choose not to accept the quest in the first place. With this system, players can skip interactions with characters they’re not interested in, giving them more agency over how they experience the story. However, to ensure the corruption level increases, certain actions such as groping and teasing by other NPCs will be unavoidable.
I suspect that having this be Unavoidable will be a dividing line, regarding interest in the game. Making it unavoidable will probably cost you a fair number of players/$upporters
Only the actual sex scenes will remain fully up to the player's choice. I don't believe a completely "pure love story" route would attract much interest
Firstly, pure love stories as a whole (and if well written/executed) tend to attract the larger player base(s). You might want to check some of the more popular Adult games, most (if not all) of the top games tend to have some variation of a "Pure Love" route.
Overall the idea for the game seems decent enough, but anytime you add an unavoidable fetish, you are going to cut off a portion of your player base. To be clear, I fully support any Dev having the freedom to make exactly whatever game they want (If I don't like it, I'll just ignore it). That being said, if your goal is to make a /sharing/swinging/free love/whatever style of game. I would recommend you be very clear with everyone about it.
You have done a good job by saying that you want sharing elements, that your not really into the idea of full cuck ntr (though I would argue that depending on some peoples viewpoints, these can be considered the same thing).
I would recommend (and I am sure someone else did or will);
Put your expected future tags on the front page.
Explain if any/all/some fetish content (like sharing, cucking or whatever) is avoidable (as in it can be prevented, or made to not happen though the players choice and action).
If it is 'skippable' (as in, it still happens but the player can choose to not see the scene).
I would also include any fetish that is unavoidable, this is very important as it will allow those players who have zero to low tollerance for the games fetishes to move on. This will be better for you and for them.
Last thing I would recommend is not to assume something is going to be 'ok' or fine because its 'mild - in your opinion'.
Players of adult games have a WIDE range of tollerance for what they dislike.
Some will say that its (technically) not NTR, if a LI breaks up with the MC at 2pm, sleeps with the whole football team at 3pm, then gets back together with the MC at 4pm.
Others consider it NTR if a video of the LI having sex is shown to the MC.
Some say girl - on - girl is "hot and sexy". Others will say its cheating/ntr.
So I strongly recommend that you do not assume some level of something is going to be 'fine' with they playerbase. This is why the question 'Is it Avoidable' is asked about 100 times on EVERY THREAD.
Be transparant, be upfront and be honest. This WILL reduce your place base, but thats probably for the better as it will remove people who were never going to like your game.
You cannot please everyone (which is a fact that many dev's forget), and I don't recommend you try.
All that said, good luck with the game.
