Hi brickbones. Welcome to the world of game development. What games are you interesting in develop? already choose/learn and engine?

Some advices:

-Always start small. Not big games, don't try to make a GTA or a COD first. Start small (like a VN or a prototype not for publishing). 

-Do not pirate the tools you use. If some tool is commercial, buy it, to avoid any legal problem in the future.

-Do not use AI as a replacement. AI is not a replacement, is a tool, or something more like an assistant. It may create some small code and pretty drawings, but when you need to create things bigger and functional, you will need the knowledge (in arts, music, etc) or a professional's help. 

-Read licenses and ToS. Many of the things you can or can not do are explained there. Also, how much a big company can affect/control your work. (Example: Unity situation, so beware of SaaS)

-Don't marry with anything. Learn how to do stuff, not how to use a specific tool/program. If in the future you need to change the tools, it will be less painful.

-Remember to take rests from time to time. Don't overwork yourself. (The only person responsible for your well being in yourself.)

I hope i didn't scare you, wasn't my intention, just give you a little hand/head start. Don't be afraid of making question. There is no stupid question. Everybody was a newbie once.

And good luck. 

I made a copy paste from another post. haha. Anyway, wish you luck.

hi, im also a web dev in my company.

there are some games made in pure html+css+js and a backend behind. I love this kind of architecture because you can change client (other interface, better graphics) and game still work.

btw for many advances gendres of games your life will be a lot better using an engine (unity, unreal, rpgmaker).

Some smaller ideas could be done with only libraries (phaser, aframe, ...). More easy than a full engine but need to know what you are doing.

IA is a powerfull tool today but also need to know what IA is doing, or your proyect will be hard to add features in future.

Finally, if you are starting, dont worry about licenses, or legal stuff (im from latam :P). Your game will not generate a lot of money so dont worry about that. Is better practice with a lot of external solutions to have an idea about how do stuff.

An example is https://teamwood.itch.io/super-auto-pets
Very know game where players "create" a formations and send it to server. The server do a match with another formations sended by other players in the past and return to player the played match. Is like a multiplayer in real time but opponent in no real time. I think many auto-battles games are like that.
You dont need an engine to do that, only html+css+js+backend/database

im also doing a game now with the same idea using free database and phpserver services.

Finally 2, like dream say, start small. Maybe only do a mechanic and play with it. Many people waste a lot of time doing all levels and art and dialogues and "visual stuff" but later they can't spend three days making the character jump and the proyect never end.
