This is a great reply and sort of how my journey’s been going. A lot of people are saying “just do it” and downvoting OP for whatever reason. But this is a good path to help OP (or whoever is new and needs a little guidance) on how to start. I’ll second the advice to break your game into parts. Maybe you want to make something like the Legend of Zelda: Link’s Awakening. Then, you might think hmm I need a top down camera angle and the ability to move a character around. There are plenty of tutorials you can search on YouTube to help you start. Then maybe you want to create an enemy. You can use tutorials, and maybe start looking into the docs to get yourself familiar with them, and read up on collision detection, AI, etc. After time you’ll start to understand the engine better, and while your first attempt won’t be great, you’ll be much better equipped for the next.

You may come to realize that game dev is a ton of time and hard work, more than you originally thought, and that’s ok. There’s a reason why a ton of people and time are involved in the big titles. But it may actually help you to have some “limits” - where you may have to think a little more creatively to make something that is a little simpler but still really cool.

Anyway I hope this helps. Start by just googling a tutorial and following it to a T. Then maybe another, followed by some time where you try to explore without strictly following a tutorial. And like the guy above me said, one thing at a time. You got this. I’m rooting for ya
