For example, if someone wants to create a puzzle game, it might start by brainstorming ideas related to puzzles, such as word puzzles, number puzzles, or logic puzzles.
From there, it could generate more specific ideas, such as a game where players have to solve math problems to progress, or a game where players have to match colors to progress.
Another example is creating a first-person shooter game. You might brainstorm ideas related to first-person shooters, such as different weapons, settings, or enemies.
From there, you could generate more specific ideas, such as a game set in a post-apocalyptic world where players have to fight off zombies, or a game set in outer space where players have to defend their spaceship from aliens.
