There is no perfect model to craft a story. It depends a lot on the type of game you are creating.
The Emotional Journey is not supposed to be a template to follow but more of a guide. This below is the approximate workflow I use when I tackle a new story. I wish it would be as straightforward as it looks, unfortunately, there is a lot of back and forth between steps during the work.
Those steps help me focus and get inspired when I feel blocked.
