The story is boring. Adult games with no sex are no good.
I like the NMM story.
It has world-building and good characters, IMO, with a fair bit of variety.
There are enough LIs that most of us can find one or more to enjoy as part of the journey.
The story gives context to 'why' the characters are who they are.
If you are truly bored with this story - if it really means nothing to you - all that is left are pretty pictures and animations of characters that are then almost meaningless - so why not just go to PornHub instead ...
I find the best AVNs spend time to build the world, establish who the characters are, then take me on a journey that will, in time, include adult relationships, including sex.
There are plenty of people on F95 who complain about the time it takes to build up to the different kinds of sex, but in most cases, it is not milking by the dev, it is just storytelling and world-building so that the relationships have a 'why' for Any shared intimacy.
Whether you are 20 years old or 70 years old, your time has value so why not spend it on stories that don't bore you?
Cheers!!
