Yes we can of course
But maybe there is a story what HNStudy wanted to tell if you know what I mean. Finishing a story/game/novel gives a satisfaction and accomplishment for the author. That doesn't mean it can't be continued with same characters and story, it simply would be taking place after the holiday for example, and it would name different so Takenote can be a finished product in the future.
But it can be a total new story with the same/similar character just different name etc...
My point is as long as he is gets his goals from this beautiful hobby we can still get kinetic novels from him
Btw I like the idea that every now on then, if we throw around some plot ideas, who knows maybe he will like some of them so much to put in pictures
