Of course, but when the game try to be realist, then doesn't he need to be it even for this ?
I don't say that all games should works like that, but it don't surprise me when they do, and I'll not dislike them solely for this.
That's the main point of the problem. The consequences of a choice matters, but the offered options matters equally.
What was an author thinking while giving such choice ? Few players will choice this option, and most of those who'll do it, will do it only once, to see if choices really have consequences. But, perhaps more importantly, what was the player expecting while picking it ? It's obvious that the answer will not be, "great, come take my ass, starting now I'm your dirty anal sex slave".
I think that it's more the fear to write a simple kinetic novel, than anything else. Some kind of, "I'll give them choice, this way they'll see my story as being an effective game". But then, they've to face the truth, if you give choices, you've to take count of them ; at least for a time, the story will not be the same if you kiss the girl, and if you don't. Which obviously imply more works on the story, and more complexity to make the game.
Therefore, some (too many) authors goes for the easiest solution. Either they make totally obvious choice, knowing that 99% of the players will follow them, and that the other will perhaps complain about a lack of constancy but it doesn't matter, it's only 1% of them. Or they go for the game over solution ; you don't need to write a variation where the MC haven't kissed the girl, if you end the game when the MC don't kiss her.
Which fall back to what I said about bad consequences. The same should be applied for good ones, and you'll not have sex because you made a good choice, but because you made many of them. Something like :
You're on a date with the girl, you talk, you act, you've to face a total of 10 choices being globally "good one", "neutral one", "bad one" ; with potentially one or to "what a wonderful move you just made !".
- More than 3 bad choices, sorry, you're terrible she don't want to see you again ;
- Less than 3 good choices, she don't hate you, but you're clearly not the right for her, let's stay friends ?
- Between 3 and 5 good choices, she'll kiss you and want to see you again ;
- Between 6 and 9 good choices, she'll give you a blowjob ;
- All 10 good choices ? Score, you'll have sex on the first date.
Of course, there will be compulsive players that will want to have sex on the first date, but I'm sure that most players will agree with the blowjob, or even just the kiss. It don't close the door, you're just playing the game your way, having the feeling that you're slowly seducing the girl and not just here to fuck her.
Anyway, the next date will make you starts with part of the earned points ; enough to make you have at least the next step this time, unless you make really bad moves. So if she just kissed you on the first date, you'll have at least a blowjob this time.
And so on for a total of four/five consecutive dates, even if you had sex on the first day. She want to know you, so before being effectively involved in a relationship, you'll have to pass through those dates and at least not fail them. Those who goes fast will have sex with her everytime, the others will have a kiss, then a blowjob, then finally have sex.
Now you're on a relationship, the goal isn't anymore to have sex with her, but to try this position, or that kink. This going on a day basis, through the discussion you'll have with her.
Let's take "anal sex" as example. You've past some times together and convinced that watch porn together is funny and kinky. You've the possibility to choose a video purely with anal, or a video where you know that there's ass play, or... well, there's a lot of possibilities. You'll also talk about it, commenting the video, immediately, or few days later with something like, "Oh, I crossed a girl today, she remind me of the girls we saw ; you know, the one that was loving so much to have a plug in her ass". Slowly you'll make the girl thing about it, and the outcome will depend of the choice you made.
When she'll accept to do anal, and how opened to the idea she'll be, depending of you. It can be in a week like it can be in a month, depending if you talked about it often or not. Like she can really want it, because you made some good points, or she can do it to please you because you just convinced her to give it a try, and like it's your birthday, let's start a tradition, your anal birthday gift. In the same times, if you made too many bad choices, it will just never happen ; commenting a video by saying, "now I want to ravage your ass", isn't a good way to start opening a mind to this idea.
Here again, some players will be compulsive and want to have it fast, with the girl totally agreeing, while others will prefer to build their own story, and will already be satisfied by it being a birthday gift ; yet the birthday gift can become more than if you continue talking about it, proposing other way to do it that she'll perhaps prefer, or saying that she seemed to have liked it at least a little.
It's up to the player to choose what seem to be the right choice depending of what he want. This knowing that globally speaking, unless you make a really dick move, you'll not close the door, just delay it and/or lower the result at first.
Too many authors want to go too fast. It's the update with anal sex, you'll have anal sex if you make one choice right ; and don't worry, the choice will be between, "let's have anal sex" and "I'm tired, let's just sleep tonight".
Perhaps that I'm an exception, but I prefer when it's more subtle.
I think that, except at their paroxysm (see above), choices should have small consequences.
You picked the right color, she'll be happy during the rest of the day, perhaps even more enthusiastic when you'll have sex. Then it's all, the next day she'll be back to her normal self, just a little more happy than usual. And the more you'll make good choice, the more her normal self will be full of happiness.
And if you pick the wrong color, next time you'll be at the restaurant she could say something like, "and please, since you don't even know what color I prefer, let me choose what I'll eat". Then again, if you tend to make only the wrong choice, she'll be less and less happy ; you don't care enough about her, do you even really love her ?
Like I implied, it's a slow build. No real wrong choice, no real right one either. A grinding mechanism in a way, but that don't feel wrong or boring, because it don't rely on repetitive action, just on the need to do the right choice more often than the wrong one.
All of those choice being inside scenes that will happen only once or, for the "watch porn together" by example, that will defer enough to not feel repetitive even if, globally speaking, the action is the same.
