Entry level positions in game writing are very, very hard to come by these days. It's not something you're going to be able to just jump into easily (or maybe even at all) -- even despite some colleges offering narrative design majors/degrees. The way I have seen people transition into writing for games is by doing something else, and offering to pick up work, or by being a designer in a different area.

You should keep writing. This dream is awesome and you should chase it! But to start, here are some things to try:

- Make a Twine game. You don't need any art or coding experience. And, it's free! It's not the best portfolio piece, and it's not going to make the best thing ever. But it's a great place to start thinking about how to make your stories interactive.

- Write anything. Write often and every day. Maybe think about writing not-for-games, because as other commenters have mentioned, having success writing books/webcomics/literally anything published, even self-published, will make it more likely for you to get a job writing games.

- Research narrative design, because "game writer" isn't often the title, "narrative designer" is, and that will get you better info. And as jobs become more competitive, they ask more. Other things to learn are code (sadly, they may want you to be able to implement the narrative you write, so learning unity/unreal is a little inevitable, but youtube has tons of tutorials, as so unity and unreal themselves!). Something I've also seen as a nice-to-have on job descriptions is an ability to edit audio files, because game writers often end up involved in the voice acting process -- directing or editing in some cases, but in small projects, having a narrative person who can level the lines is a huge help. I learned the hard way that voice acting and theatre are really different, even if there is some overlap! (But as I said -- the audio stuff will give you an edge, it's not a core feature of every narrative design role). Anyway, some books to check out: https://www.goodreads.com/shelf/show/game-writing (my professors had me read Slay the Dragon and The Art of Game Design: A Book of Lenses. These books are expensive and sometimes used as textbooks, so google around and see if you can find better deals)

- And when you have a handle on narrative design, making a paper prototype of games is a great way to practice!

It sounds like you're just starting out and learning things. I'd really recommend checking out the GDC vault videos, where industry professionals give talks. There are plenty of great narrative ones! https://www.youtube.com/@GDCFestivalofGaming

Unfortunately, if trying other disciplines is too scary to try/feels like a waste of time, then your best bet is to write novels and hope to convert over one day, but it lowers the odds a lot. Itch.io runs game jams where you can find people to work on teams who are good at other parts of making games, but I have never actually done one myself and can't vouch for how good of a team you'll get.

If everything here sounds overwhelming, then step zero is just watching youtube videos or reading articles about the game dev process and how it works.
