These scenes were only ever intended to be viewed as almost non canon bonus content, containing over the top, raunchy little stories for those who'd like that kind of thing. Admittedly, it was also a way of adding some more X rated scenes into these earlier episodes in a way that wouldn't disrupt the flow of the present story or development of the characters. Obviously some people feel it tarnishes their opinion of Grace moving forward, but I guess by making them avoidable, questionable in their truth, and the fact that it happened near two decades ago, I'd hoped that would be enough for non fans to at least be tolerant of it. But perhaps I underestimated some peoples sensitivity towards these types of scenes.
The thing is, at the end of the day, we're just a bunch of people doing our best to create the most enjoyable games we can, and sometimes for better or worse that means trying to make everyone happy, which I should know by now is a fools errand. I just wish more people would realize this when they start on their crusades to tear our and other developers games to shreds.
Trying to please everyone is indeed a fool's errand and I strongly suggest you don't try and do that.
My recommendation after playing is that you let fans know clearly exactly what type of content you are going to have in the future and if it is avoidable/skippable. This helps a great deal for people who get invested in a story, but don't want unavoidable *Whatever*. Let them know so they can decide to stay/move on, if they do move on, they were never your target demographic anyway. Also, it's perfectly fine to make mistakes, it's part of the learning and development process (don't I know it). It's also ok to admit it when you made a mistake, though this will inexorably lead to being asked to 'fix' it.
The golden rule of game development;
Haters are always going to hate, and bitchers are always going to bitch.
If you stick to your plans, are clear and direct with supporters, and admit/learn from mistakes, you will find that most reasonable players will be accepting and understanding (which are the only type your ever going to satisfy).
Personally, I can say that I only ever get pissed off at developers under two very specific conditions.
1)The game moves away from the original promises made by the Dev's after I have contributed/invested time/money.
This is an easy mistake to make and typically done in some kind of attempt to 'bring in more fans' or appeal to a greater audience or something similar. I've studied this phenomenon to a fairly deep level (not for
adult games, but that specification seems to sharpen the results, not soften them). It is almost universally true that attempting to broaden appeal comes at the cost of sacrificing something that your core stakeholders value. Sometimes the 'small loss' has a 'greater gain' but in many cases, this results in a net loss of supporters. This is doubly true if such moves are made to appeal to a much smaller or niche group. This is why I always recommend that Devs have a plan/outline for their games and stick to it.
2) If a Dev lies to the player base.
Either by purposely misrepresenting content or by presenting content in a way that 'technically' qualifies it as one type, when broad interpretation will be another. If you have to qualify a statement with the word "Technically", then you should probably rethink the real-world implications and effects of that statement. I think some people on f95 call this 'camouflaging' or 'tag avoiding'.
In any case, I hope the feedback is helpful. While I am going to skip the first game (it doesn't seem to be on the same standard as this one), I look forward to seeing where you go with this one. So far the story has been well written.
Best of Luck!
