I wanna create a game like dead by daylight

So I been wanting to create a game like dead by daylight or something like that a horror survive multiplayer game where someone plays a monster and 3 other people try to escape but I don't know where to start or how to start.

1. learn how to use sb. 2. learn how games in general work (variable declaration, the main loop, input handling, etc.). 3. plan out how you'll make your game (if you're basing it off another, learn how it works and see how you can make some mechanics match). 4. put all your plans into a code form and be sure to organize (and document if you want) all the mechanics, sections, etc. if it's a large game. 5. hopefully after you've put enough effort into it and it's worth playing go ahead and upload it to sb's server and share the key! There's other ways to share your program such as cfw or petit modem but you can look into that.

Start small! Trying to make big things in the beginning without a proper foundation makes it very hard to stick to it, and the final product will be low-quality. I'd say stick to spaceturtle's plan, but add a few simple (not just in mechanics or gameplay, but code itself) games that you can make in there. Or a lot, if you're an overacheiver.
