It would take quite a lot of time or the power of outsourced specialists.

Yes, it is possible to make a game from scratch as a beginner in the game development business. However, the time and effort required will vary depending on the complexity and scope of the game you want to create. Developing a simple game can be a good starting point for beginners.

Here are some key steps and considerations:

Define your game concept: Start by brainstorming and deciding what type of game you want to create. Think about the genre, mechanics, art style, and target audience.

Learn game development basics: Familiarize yourself with the fundamentals of game development, including programming languages, game engines, and design principles. Popular game engines like Unity or Unreal Engine are beginner-friendly and have extensive learning resources available.

Acquire necessary skills: Depending on the type of game you want to create, you may need to learn programming, game design, art, sound design, or other relevant skills. Online tutorials, courses, and documentation can help you learn these skills.

Plan your game: Create a detailed game design document outlining the mechanics, levels, art assets, and other essential elements of your game. Planning ahead will save time and make the development process smoother.

Start small: As a beginner, it's advisable to start with a small, achievable project. This allows you to focus on learning and completing a game within a reasonable timeframe. Simple puzzle games or 2D platformers are good examples of beginner-friendly projects.

Iterate and refine: Game development is an iterative process. Start with basic functionality and gradually add features, polish the gameplay, and refine the art and sound. Seek feedback from others and make improvements based on their suggestions.

Allocate time and effort: The amount of time and effort required will depend on various factors such as your familiarity with the tools, complexity of the game, and the skills you need to learn. Game development can be time-consuming, so be prepared to dedicate consistent effort and be patient with your progress.

Overall, it's difficult to provide an exact estimate of the time required, as it can vary widely. It could take weeks to months or even longer for more complex projects. The key is to remain motivated, break down the development process into manageable tasks, and continue learning and improving your skills along the way.
