That actually sounds pretty awesome. There hasn’t been a game like this? I’m honestly surprised.
It's basically what you get when you take combat out of RPGs, or perhaps the crunchy farming/dating sim elements out of farming/dating sims (though they generally have less plot flexibility, or plot in general). I haven't come across a pure VN which managed such a level of complexity.
If you don't want to go to the trouble of writing stories yourself, playing a good RPG minus the parts where you beat stuff up comes pretty close. I do both and the latter is definitely easier, at least.
