The Beginners Guide To Basic Video Game Development
Find out how to go from idea to reality with your first video game.

1. What’s the BIG IDEA for your video game?
The best place to start with making a video game is “THE BIG IDEA!” What does that mean? It means that you should have a strong idea about what makes your game special and different from other games. Your game doesn’t need to be completely different. After all, there are a lot of games that are similar to each other, and they are all fun, and that’s great. But if you want your game to be successful, you need to know what is the one thing that will set it apart from the others.

Here are some examples of big ideas in popular games
Let’s look at some games you probably know and what their “big ideas” might have been:
- Minecraft: Minecraft’s big idea is creative freedom. In a simple, blocky world, you can explore, build, and create anything you can imagine. There isn’t a specific storyline; the player sets their own goals, whether it’s building a massive castle, surviving against monsters, or even creating a rollercoaster. The entire game revolves around the endless possibilities of building and crafting, giving players a world to make uniquely theirs.
- Among Us: Among Us has a unique twist on teamwork and betrayal. The game’s big idea is hidden identity—where players work together to complete tasks on a spaceship, but one or more of them are imposters trying to sabotage and eliminate the crew. The tension comes from not knowing who to trust, which creates excitement as players debate, accuse, and try to figure out the imposter’s identity.
- Pokémon: Pokémon’s big idea is collecting and battling creatures. The thrill of the game is in exploring the world, discovering new Pokémon, catching them, and training them to battle against other trainers. Players are motivated by a desire to “catch ’em all” and build a powerful team, combining exploration with strategy in battles.
- Fortnite: Fortnite combines battle royale with creative building mechanics. Players aren’t just trying to survive as the last one standing—they’re also building forts, walls, and other structures in real-time to protect themselves or gain a strategic advantage. This mix of fast-paced combat and creativity makes it stand out from other battle royale games.
When coming up with the big idea for your game, think about what will make it exciting and memorable. Maybe you love mystery and want to create a game where players uncover secrets on a haunted island. Or maybe you want to make a game where players must grow a garden on an alien planet while defending it from strange creatures.
Whatever you choose, start with this one unique concept and build everything around it. If you’re having trouble coming up with a big idea, think about what you love in other games, movies, or stories, and see if you can add your own twist to it. Remember, the best games have a clear big idea that players instantly understand and get excited about!
2. Make a Game Design Document.
A “GDD” is a “Game Design Document,” and that’s what you should make next. What goes in a GDD? EVERYTHING. This is where you put all of your ideas, and show how they make your “Big Idea” shine! What is the plot/story of your game? Who are the characters or teams? How does the game work? Is it single player or multi-player? Is it a first person shooter? Is it a side-scrolling actioner? Is it a puzzle game? What are the tools, objects, or weapons? Is it 2D or 3D? Is it for the computer or for the iPad?
A professional GDD can be as long as 50 pages or more. Yours doesn’t have to be. But, if your GDD is less than one page long, that probably means that you need to do more thinking and more imagining to really have a good idea about what kind of game you are trying to build. So get to imagining, and write down everything you think of!

Here's a simple format you can follow:
1. Game Title and Big Idea
- Title: What’s the name of your game?
- Big Idea: In one or two sentences, describe what makes your game special or different from other games. For example, “In my game, players are magical cats who defend their home from alien dogs!”
2. Game Summary
- Genre: What type of game is it? (Adventure, puzzle, role-playing, platformer, etc.)
- Objective: What is the main goal of the game? (Survive the alien dog invasion, collect magical gems, rescue lost animals, etc.)
- Storyline: Write a short story about the game world and what the player’s character is trying to achieve.
3. Characters and Setting
- Main Characters: Who is the player, and who are the other main characters? (Include a quick description for each one.)
- Setting: Describe where the game takes place. Is it a magical forest, a city in space, or an underwater kingdom?
4. Gameplay Mechanics
- Actions: What can the player do in the game? Can they jump, run, shoot, or solve puzzles?
- Controls: Describe the basic controls. (Arrow keys to move, space bar to jump, etc.)
- Levels or Stages: How will the game progress? Are there levels, or is it one long journey?
5. Visuals and Sounds
- Art Style: Will the game look realistic or cartoonish? (2D or 3D, colorful or spooky?)
- Music and Sounds: What type of music and sound effects will you use? (Peaceful forest sounds, upbeat action music, magical sparkle sound effects.)
6. Challenges and Rewards
- Enemies and Obstacles: What challenges will the player face? (Monsters, traps, puzzles, etc.)
- Rewards: What does the player earn for completing tasks or levels? (Points, coins, new abilities, etc.)
7. Additional Ideas
- Special Features: Is there anything extra that makes your game unique? (Power-ups, hidden levels, funny dialogue, etc.)
- Notes: Add any other ideas here that you think might be fun for your game.
To give you an idea of what your document might look like, here's an example GDD:
- Title: Magical Cat Defenders
- Big Idea: Players become magical cats defending their forest home from an invasion of alien dogs.
- Genre: Action Adventure
- Objective: Stop the alien dogs from taking over by finding and using magical crystals.
- Characters: Sparkle the Cat (the hero), Shadow the Cat (friend with powers), and Ruff the Alien Dog (main villain).
- Setting: An enchanted forest with glowing trees, waterfalls, and caves.
- Actions: The player can jump, climb, and cast spells.
- Art Style: Bright, magical 2D cartoon style with sparkles and glowing colors.
3. Choose a Game Engine.
Now that you have a strong idea of what your game will be like, it is time to choose a game engine. A game engine is a piece of software or a website that is made to help you build a game. A long time ago, there were no game engines to help, but now game engines can do a tremendous amount of work so that you can just focus on making a fun game.
There are a lot of game engines to choose from now, so how do we choose? Well, a lot of the choice can be determined by what you wrote in your GDD. For example, if you decided that your game is a Role-Playing Game, a great choice would be RPGMaker! If your game is a simple 2D action game, a great choice would be Scratch or GameMaker. If you want your game to run on Roblox, you should use Roblox Studio. And if you want to make a professional-level game, and if you are at least in high school, you can go with Unity.
4. Decide on your resources.
With today’s helpful game engines, small games can be made with just one or two people. Often there is someone to code the game and someone to make the art. But, this doesn’t have to be the case. Sometimes the same person does both things. Or sometimes there is just a designer and an artist.
If you are not an artist, you may be able to find free art that is included by your game engine. Scratch has its own library of 2D images. Roblox has the Toolbox system, where you can find 2D images, 3D models, tools, sounds, music and even code! And Unity has the Asset Store, which is just like Roblox’s Toolbox. So you may be able to find all the art that you need instead of having to make it yourself. Also remember that the internet is a great resource. If you are making a game just for fun, for yourself, (not selling it for money or sharing it) feel free to use any images, sounds, and music you can find on Google. Or use free image sites such as Canva and Pexels.
5. Prototype and playtest your game!
A game prototype is a very small version of your game that demonstrates what your game will be like. It has some basic art, user interface, and most importantly, it demonstrates the key game mechanics that the player will use to play and beat your game.
Creating a game prototype is a key step to making your game, because this is where you prove that your game is fun and that people will want to play it. Once your game prototype is ready, you can host playtests. Playtests are where you show your game to your friends and family and let them play it. The goal of a playtest is to see what works and what doesn’t work, what is fun for your players and what is not fun for them, what the players understand and what they don’t understand. After each playtest you can improve your game so that it gets better and better!

5. Complete your main video game development.
So, you have written a GDD about your Big Idea, you chose a game engine, and built and playtested a prototype of your game. Everything is looking great! Now it’s time to go from idea to full-blown game. This phase of development is where you express your creativity as you make all of the levels and add all of the story. Also, it is where you will do all of the extra stuff that will make your game shine, like adding sound effects, visual effects, music, etc.

6. Publish your game.
Once you have built out all the levels of your game, added the beauty and polish to it, and tested it for bugs, it is time to publish your game. Publishing means taking the game that you have been working on and putting it in public for the world to play!
A lot of game engines have places on their websites where you can publish and share your game with the world. If you made your game with Scratch or Roblox, you will also get a website link that you can send to friends and family so that they can play your game. If you make a more formal game, like with Unity, you may host your game on a website or you may choose to publish it on a game publishing platform such as Steam or Epic Games Store.
Congratulations! You made a game!
