Not to discourage you from learning to program but, if you already have an abundance of written material, why are you not looking at doing a book or a comic or a tabletop game of some kind instead? Something that doesn't require years to learn a technical skill before you're able to introduce your vision to the public. If you do have a passion for programming and you learn enough to begin making games, consider that if you've been writing and publishing all this time you would have all this IP at your disposal that has already been exposed to the public and have a measured response for.
Several reasons. I find that video games are a great storytelling medium since you get to interact the the characters and world. The Last of Us had me care more about the characters than any comic, book, or movie did. Plus, I figured a game would have a bigger audience. I don't really care about the money, I just want to share my universe. The best book publishers usually require giving away some of the rights to the ip. I did plan on self publishing a book series that had a shared universe with the game. I seriously considered comics but a video game would make the world that much more believable in my opinion since it would be in motion and had actual sound and emotional expressions. I eventually plan on starting a game/animation studio. I find that animation shouldn't just be for young audiences.
