When I wanted to make a game, I realize that I needs papers and a pencil to come up with some ideas. As a teenager, I used to come up with ideas by just writing down the names of ideas and put them in a folder which wasn't enough information to use for game design, and I also practicing writing stories for a game project but it didn't turned out well and it was hard for me to come up with a story.
As an adult, I started to come up with ideas and give them details to give it some image and effect. As an adult, I didn't know how to come up with story ideas or actually write a story so what I did was get a book from the library called "How to write a story?" and take notes so that I can get some story ideas and write down events to use for my story which was a useful source for game development.
