I looked for a book on Amazon and found Game Engine Architecture. As I don't want to buy it and give it the same fate,
has anybody read it? What does it help you build?
It's not a tutorial, but more of a textbook. It doesn't guide you to build anything. It educates you on the general concepts of game engines and associated tools and topics.
And I consider it _mandatory reading_ for anyone interested in game engines. Acquiring the same base level of knowledge as that book provides on your own will take years of practice and acquiring answers to thousands of questions that you don't even know to ask.
Following that, don't start by trying to write an engine. Start by using a premade engine. You need to gain hands-on experience with what an engine actually does before you're going to be even remotely qualified to write your own. If you have never even used an asset pipeline before, or don't even know what one is, how are you going to make a functional one of your owm?
Go spend some time with tutorials for Unity, Unreal, Game Maker, or all of the above for a while. Learn how they work and figure out what you like or dislike about each of them. Learn what kinds of facilities they offer and why.
Then come back to whether you even still want to write an engine of your own. I mean, in this day and age of free commoditized AAA game engines, writing your own engine is utterly pointless for anything other than funsies, but that's your call.
Look, games are really hard. There's no single book that's going to take you from nothing to making anything especially interesting _and_ teach you how to make a from-scratch game engine at the same time. It's not possible. You're going to need a small library of books, a lot of time on your hands, and a willingness to ask a lot of questions.
Preferably you'd also immerse yourself in a group with similar interests and available mentoring, e.g. enter a game-focused university degree program (many well-known and highly-regarded schools have one these days) or a join a local game development club.
