Do you have an idea for a game you wish you could play rolling around in your head? And no one is making it? I've got good news for you: there are more tools and support than ever to help people who have no experience with coding or development start to learn how to create the games of their dreams. If no one is making what you want to play, why not learn how to make it yourself?
Start small, and be ready to fail.
Before you get too excited, please realize that, as with any other skill, learning how to design and develop games takes time and practice. Your first game won't look like the polished games you're used to playing, much like your first drawing won't come out looking like Monet. This is absolutely fine. My first game has a huge bug in it that causes it to break for about half of its users. I was unable to figure out how to fix it.
You should shoot for what developers call a prototype: a smaller version of your idea with a few working mechanics, a prototype that lets you see how your game plays, allows you to improve the design, and forms the foundation that you can later build upon to make a full game.
As you make your first game, you will also experience the same thing every other developer has: "feature creep" or issues with scope. You will likely want to put too much into your first game—too many mechanics, too much content. Your ambition will push your toward any number of traps. This is okay, as long as you fix it or "scope down".
A video game developer is a software developer that specializes in video game development – the process and related disciplines of creating video games. A game developer can range from one person who undertakes all tasks to a large business with employee responsibilities split between individual disciplines, such as programming, design, art, testing, etc. Most game development companies have video game publisher financial and usually marketing support. Self-funded developers are known as independent or indie developers and usually make indie games.
A developer may specialize in a certain video game console (such as Nintendo's Nintendo Switch, Microsoft's Xbox One, Sony's PlayStation 4), or may develop for a number of systems (including personal computers and mobile devices). Video-game developers specialize in certain types of games (such as role-playing video games or first-person shooters). Some focus on porting games from one system to another, or translating games from one language to another. Less commonly, some do software-development work in addition to games.
Most video game publishers maintain development studios (such as Electronic Arts's EA Canada, Square Enix's studios, Activision's Radical Entertainment, Nintendo EAD and Sony's Polyphony Digital and Naughty Dog). However, since publishing is still their primary activity they are generally described as "publishers" rather than "developers". Developers may be private as well (such as how Bungie was, the company which developed the Halo series exclusive to Microsoft's Xbox).
