If you both enjoy playing video games and drawing, telling stories, or creating art, you may have wondered how to make a video game yourself. The good news is that the internet's array of free, open-source game engines have made this easier than ever before!

If you have the desire and the vision, you can make your vision a reality. Making your own video game is now as easy as conceptualizing and designing your dream game, then downloading free tools to build it.

Read on to learn how to make a video game using free tools available online.

1. Set realistic expectations.

Dream big, but stay grounded in reality. New titles saturate the indie game market each year. Many meet with little success. Only 37 titles were released via video game distributor Steam during its first year, 2004. In 2021, developers released 10,696 games on the platform.

Even if your first game fails to turn a profit, it represents an important stepping stone in learning how to become a video game developer. You may even earn a small audience to boost you towards future success.

2. Start with an idea.

Every interesting work of art begins with a creative spark. The most fun part of making your own video game might be brainstorming. When brainstorming, make up your mind on a few key aspects of your game:

• Genre: Platformer, survival horror, puzzle, etc.
• 2D vs. 3D: 3D games are more difficult to make, particularly if you don't want to use premade tools.
• Premise: An interesting story keeps players engaged.

Prioritize ideas that play to your strengths, sound fun to you, and fit within your budget.

3. Research, brainstorm, and create a design document.

Once your ideas solidify, develop a game design document (GDD). This document, which could be a Word document, PDF, or Google Docs document, lays out your blueprint for your game and establishes a creative vision. Your GDD should include:

• Story
• Characters
• Level/environment design
• Gameplay mechanics
• User interface and controls

Also, decide on a programming language or to use a game development tool that doesn't require coding. C++, Java, and JavaScript are the main programming languages used in game development. The latter two are among the easiest programming languages.

4. Choose your tools.
