Definitely not the only one. Even the developer wants to see some basketball.

(Will prob put a version of this in mind drop 43)
But with that being said I always find it important to clarify that this is an erotic visual novel with some basketball in it driving the overall plot, not a basketball story with porn elements.
I've only seen like a season of it but think of how a show like "Friday Night Lights" works. In it, football is shown often and drives the situation characters find themselves in but ultimately is only showcased when it needs to be. The overall quantity of content comes from character interaction.
And just so it's clear, there's no basketball mini-game or anything. The player does affect games but through choices on and off the court not some mini-game or whatever.
Some games will be long and shown in detail, others won't be shown at all but rather talked about.
Basketball is obviously an important and necessary element of the story and will drive everything forward... but the main focus of the game is the girls.
I think a healthy balance that I aim to achieve is 15-20% basketball, 80-85% erotic VN.
