Game Development from Zero Knowledge
When you think of game development, don’t you imagine things like, “It’s impossible without programming skills” or “You need specialized knowledge”?
But that’s no longer the case. With AI and no-code tools, even beginners can turn the games they imagine in their minds into reality.
In this article, I’ll show how even people who can’t code can create a game on their own, introducing specific tools and practical ideas for using them.
Game Development Has Shifted from a “Difficult Era” to an “Anyone Can Do It” Era
In the past, creating a game required learning programming languages like Unity, C++, or JavaScript. However, recent developments have dramatically changed the landscape:
- Advancement of No-Code Tools
→ Tools now allow you to create games using drag-and-drop operations - Utilization of Generative AI
→ AI can automatically generate images, BGM, dialogue, and characters - Lowered Barriers for Solo Developers
→ Small teams or even individuals can produce commercial-level games
In short, the notion that “if you can’t code, you can’t make a game” is now a thing of the past.
What Are No-Code Tools? 5 Beginner-Friendly Platforms
No-code tools are development platforms that allow you to create apps or games without programming. Here are some tools that support Japanese and are especially easy for beginners to use:
