A video game designer decides how a game plays and then proves it works. You write the rules, build the challenges, tune the numbers, and keep everyone on the team aligned through clear documents. Nobody hires you for ideas alone; they hire you for playable prototypes, sound reasoning, and the ability to take feedback. This roadmap takes you from learning how games work, to building small finished games for a portfolio, to owning systems on a team. Everything here is free. Most US studios want a bachelor's degree or equivalent proof, and a portfolio of shipped or playable projects is what gets

Stage 1 of 3 · about 12 weeks
Understand why games are fun, and build your first tiny playable games using a free engine.
Core game design theory
Every design choice answers a question: what does the player do, and why do they want to do it again? The core loop, challenge and reward, and player motivation are the vocabulary you will use in every design review.
Prototyping in a free engine
A design you cannot play is only an opinion. A prototype lets you test an idea in hours. Unity and Godot are both free and widely used; Unity uses C#, which appears in the job data.
Basic scripting
Designers who can script test their own ideas without waiting for a programmer. You do not need to be an expert, just able to read code, change values, and build simple logic like if the player touches X, do Y.
Design documentation
Writing is a core task of the job. A clear one-page design doc lets artists, programmers, and producers build what you imagined instead of what they guessed.
Playtesting and listening
Active listening is the top skill in the data. Players will not tell you what to fix, but watching them will. You learn to observe silently and separate what they did from what they say.
