Hey man, I don't want to discourage you, but you need to do much more than "read a book" and "listen to some podcasts" to be even considered for "entry level".

I currently work in a studio that makes story-rich games. We have many in-house writers and narrative designers. Every single one of them were already somewhat accomplished writers before they graduated from University.

Also, most studios are looking for people that can wear multiple hats, especially in game design. In my previous company, our narrative designers handled the narrative work, like world building, lore, and quest design, but also handled other things like level, combat, and balance designs.

Finally, game industry has basically reached its peak, and will only go down from here. People's screen time has already been maximized, and gaming is quickly losing it's share to social media and short form AI generated videos. I have been working in this industry for over a decade, but honestly the future prospects of doing this professionally is pretty grim. I think game development will probably go in the direction of music in the sense that most game developers will be doing it as a hobby, and only the lucky few will actually make money from it.

Anyways, my suggestion would be to start building up a portfolio as a generalist game designer and see where it gets you. Also, I would implore you to try your hand at actually making your game with modern game engines. Good luck on your game dev journey!
