I pretty much agree with you.
I have played a lot of these games, and the story is always and should be in the hands of the author.
However I do wish many of them would quite punishing the MC in such games with a bad end, just for liking sex, and all fetishes they run into. ( I do understand the BDSM area's, but even those if consensual or not crippling or fatal should not be always a reason for a bad end.)
I mean, I always though sex was a pretty good thing myself. (I think it is why the human race keeps it's population high.)
Not that I would want to be popping out a baby every nine months.
but maybe the MC could have a lot of fun, and still find fortune and fame, and a good life?
