So, the question seems vague but I will elaborate.
I’m a software developer, but I don’t do games; yet I have an urge to try and make something.
It just seems so overwhelming, I know I want to make a game where the main character is a cat and you have to complete missions, but where do you even begin. Where does the art come from? How do you refine your idea, if all you know is you want a cat game? How do you choose an engine? Do you just start with the basics and get a cat walking around and see what comes next? If you can’t hash out the idea then so you have a right to even try and make a game? Is it best to follow tutorials to get used to making games? I feel the answer to that is no as before I become a software developer, tutorial hell was a thing and I realised I needed to make things for me to actually learn.
Sorry for all the questions, this was just a stream of thought.
I recommend reading about Daisuke Amaya (a.k.a Studio Pixel) and his creation, Cave Story.
He made the game in the course of five years and moved to a less intensive and low pay job to work on the game. The man made the art, soundtrack, the program he used to compose and render the said soundtrack and the fucking game engine. He’s also called “The father of indie games”
