I imagine my story would fit for more of an open world adventure game, similarly like Zelda: Breath of The Wild but with a twist where you can switch between the characters Twiga, Nina and Shido. They have their own role around the machines of the game to advance the storyline, and a particular character will not interact with people and another character will get more rewards for a quest.
If I could I would just turn my story into a game straight up, but I don't really have the budget or time. Sigh.
