Not just how to code, but you have to have an idea, you need to know what you want to make, what you want the player to feel, either have the player critically think of his/her actions, or have the player get tense and hurry up to progress through the game, or the opposite, to take his or her time in the game. Then decided on the style of the game, it's genre, and the way you want it to look like. Knowing how to code is a factor yes, but you want more than that, you want a good story, a good motive, a good genre, memorable characters etc.
