I don’t have a point system in one of my stories. But on the other one I have, and only some of the choices matter.
And I’m planning on maybe using point system a bit more in that story. As the MC is getting personal training from this one dude, I was thinking I could use point system to make is seem that his skills are getting better. Like I’d name some people like: Strength, Speed, Reaction, Gun, Knives etc etc. And then use choices where the MC could gain point to have a better strenght, if the reader chooses right. And then the point would come in hand later on in the soty. Maybe it’ll be even so that there’s a certain amount of point he can get, and after he get’s them all then he’s done with the training.
I do like that pther sotires have point systems and choices matter, but it’s not a necessity.
