Game designer: who they are and what role they play in game development

A game designer is the architect of the game. They decide what mechanics will work, how to reward the player, where the challenge will be, and where to add the wow factor. Without them, a game project would be just a set of assets and code.

In this article, together with our expert Yevhen Kasyanenko, we will figure out who a game designer is, what they actually do, and why no sane game can do without them.

Who is a game designer and what role do they play in game development?

A game designer is a game development specialist who comes up with what can be done in the game, why it is interesting, and how to keep the gamer’s attention for a long time. Rules, mechanics, pace, emotions — all of this is their domain.

“Whether a player will be hooked from the very first seconds or will quit the game after a couple of minutes often depends on the game designer. They set the rules, come up with the mechanics, balance the difficulty and rewards. In short, they make the game interesting to play,” emphasizes our expert.

Game design as the foundation of the gaming industry

Without good game design, no graphics and no engine can save a game. It is the heart of the project. It is the game designer who decides what will happen in the game, why the player needs it all, and why they won’t want to tear themselves away from the screen. They think through what actions lead to what results, how the game rewards, punishes, and engages. It’s a delicate balancing act of emotions, interest, and dynamics. In fact, they determine what makes a game project a real game, rather than just a set of screens and buttons.

An analogy with film directing

A film director controls editing, acting, and lighting, while a game designer controls mechanics, tempo, and the reward system. It is the game designer who arranges the frames of an interactive film: where the player freezes in amazement, and where they feel a rush of adrenaline. Open a chest and get instant resources; defeat a boss and hear a loud chord of triumph and move on to the next level.

Just like a director, a designer sets the pace for the entire project, deciding what emotions the viewer-player will experience and in what order.

How a game designer differs from programmers and artists

The entire game development team resembles a film crew: each member has their own narrow but critically important role. However, it is the game designer who sets the framework within which the other specialists work. To see how responsibilities are distributed, let’s take a look at how they differ from programmers and artists:

• Programmers write code to make the intended mechanics work. Without them, the character won’t move, but they don’t come up with the mechanics themselves.
• Artists draw the world: characters, animations, interface. They make the game beautiful, but they don’t decide why the player should interact with these objects.
• The game designer sets the rules and balance. What opportunities will the player have, how much does a resource cost, what is the reward for victory, and what risks should be placed in the way? He combines creativity and technology into a single, playable system.

Without such a team, the project may be beautifully drawn and flawlessly optimized, but it will remain an empty decoration with no appeal.

The main responsibilities of a game designer

Before moving on to specific tasks, it is worth imagining a game designer as an architect. They lay the foundation, draw the floors, and determine where the doors and stairs will be. Only then do the builders (programmers) and decorators (artists) fill the project with code and graphics.

Below are the key stages for which a video game designer is responsible.

Concept development and documentation creation

Every game starts with one or two pages of a Concept Doc. In it, the game designer records:

• the hook—what will make the game stand out;
• the setting and key plot events;
• a portrait of the audience and references for the genre;
• the first set of mechanics that will reveal the idea.

“This concept document is a guide for the whole team. If, six months down the line, someone questions why we need a particular button, the answer can be found right here,” notes Yevhen Kasyanenko.

Designing mechanics and gameplay

The next step is the skeleton of the game process. At this stage, the computer game designer:

• determines the rules of interaction with the world;
• builds a system of progression and rewards;
• balances complexity and economics so that enjoyment grows without “jumps.”

In order for gamers to truly enjoy the process, it is extremely important to put in the effort at this stage.

Teamwork and communication

The game designer is also the project’s liaison. For example, they explain the math of damage to the programmer, clarify the size of a crystal with the artist, and check the logic of the game dialogue with the scriptwriter. One unclear line in the GDD (Game Design Document) can cost weeks of rework, so clear communication is half the job.

Metrics analysis and gameplay testing

After the alpha version, the numbers start coming in. It is important to see where players get stuck, which level causes a wave of exits, why a rare item is not needed by anyone, etc. The game designer spins the analytics, turning dry percentages into concrete decisions: strengthen training, lower the price of upgrades, rearrange enemies…

Quality control

In the final stage, the video game designer studies user feedback on the prototype and personally goes through the entire development process, noting even the smallest details: does the sound timing match the animation, are there any empty rooms, how does the feedback from the impact feel, etc. This is the final check that keeps the game from being “almost good.”

Types of game designers and their specializations

One person cannot be responsible for everything in game design. This field requires separate specialists who are responsible for different aspects of game creation. Let’s take a closer look at how game designers differ.

General classification by level of experience

First of all, it is important to understand that this is a profession with real growth potential. The more experience you have, the broader your area of responsibility. Here’s how it usually looks:

• Junior Game Designer – a newcomer to the industry. Writes descriptions of items and characters, sets up simple mechanics, assists seniors. Learns everything on the job as part of a team.
• Middle Game Designer – a confident specialist with 1-3 years of experience. Independently designs levels and mechanics, is responsible for balance, and actively works with other team members.
• Senior Game Designer – an expert and mentor. Leads key mechanics, coordinates junior designers, keeps the game concept in focus, and makes sure everything plays as it should.
• Lead Game Designer – a leader and strategist. Responsible for the entire game concept: from mechanics to monetization. Manages the team, communicates with producers, and ensures that the game is not only interesting but also successful on the market.

Narrow specializations

Game designer is not a single universal role. There are many areas within the profession, and each requires its own approach. Here’s who is responsible for what:

• Narrative Designer – comes up with what happens in the game. The plot, dialogues, world, lore, character personalities – all of this is their domain. They are the ones who make sure that you not only enjoy playing, but also empathize with the characters.
• Game mechanic designer – the person who makes the game fun to play. They think through how the character moves, what they can do, how their abilities work, and how they interact with the world. Their goal is to make the gameplay exciting and responsive.
• Balance game designer – makes sure the game isn’t too easy, but also doesn’t frustrate the player. They adjust the economy, enemy strength, leveling, and loot. They work to ensure that you are challenged but not frustrated.
• Combat designer – responsible for everything related to combat. How swords strike, how enemies dodge, what combos and abilities there are – that’s their domain. They make combat spectacular, the kind that you can feel in your fingertips when you touch the keyboard — almost literally.
• Level designer — builds the world you walk through. They decide where to place enemies, how to arrange cover, where the route will lead, and how to make locations feel alive and interesting.
• The technical game designer is the one who is friends with code. They work at the intersection of design and programming: they configure animations, object behavior, triggers, and event logic. So that everything works as intended.

Each of these roles is important. And the larger the project, the more precisely the tasks are divided so that the game turns out to be not just beautiful, but deep, well-thought-out, and truly exciting.

“Don’t try to hire a jack-of-all-trades. The lead sets the direction, and the specialists polish the details. This tandem gives birth to a game that you want to return to,” says Yevhen Kasyanenko.

What skills does a game designer need?

A game designer is a little bit creative, a little bit analytical, and a little bit technical. To make games that people want to play, you need to develop a whole range of diverse skills:

• Creative thinking and idea generation. Coming up with exciting mechanics, game scenarios, levels, plot twists, and challenges is a daily part of the job. No boring quest generator will help here.
• Ability to work with documentation (GDD, TDD). A Game Design Document is not a formality, but the basis of all development. A computer game designer must clearly and comprehensively describe how everything should work. Plus, you need to be able to read technical documents to be on the same wavelength as programmers.
• Basic programming knowledge (Python, C#, Lua). You don’t have to be a developer, but it’s still important to understand how code works. This helps you tweak mechanics, work with the engine, and not get confused about the technical implementation of your ideas.
• Understanding game engines (Unity, Unreal Engine). A designer needs to be able to not only come up with mechanics, but also test them in a real prototype. Unity and Unreal are the working tools of a good specialist, not something that another team does.
• Analytical and metric skills. After release, it is important to understand what is happening: where players get stuck, why they leave, what works and what doesn’t. Without analytics, it’s like flying blind.
• Knowledge of English. Almost all useful information, tutorials, documentation, and communication with international teams is in English. Without it, your opportunities will be very limited.

By developing this stack, a game designer quickly becomes indispensable: they not only generate ideas, but also turn them into clear tasks that the team can implement without unnecessary iterations and missed deadlines.

How to become a game designer: training and development

There are different ways to get into game development. You don’t always need a degree, but you definitely need to understand how games are made and why some are fun to play and others aren’t. Here are the main ways to level up and start a career in game design:

• Self-study. The classic approach is to read books, watch guides, analyze other people’s games, and dig into engines. Many strong designers started with YouTube, blogs, and Unity. The main thing is practice and consistency.
• Online courses. If you want structure and support, platforms like Coursera, Skillbox, XYZ School, and GeekBrains are a good fit. They provide theory, homework, feedback, and often projects for your portfolio.
• Universities and colleges. Many countries have universities with game design programs. They teach everything from mechanics to UX, AI, and even narrative. It’s a long road, but it’s a good foundation, especially if you’re planning a career in a large studio.
• Practice is your best teacher. Game jams, indie projects, mods for popular games—all of these give you real skills and case studies for your portfolio. The more you do yourself, the better your chances of getting into the industry. Even a simple game on an engine will be a step forward.

“The profession of a game designer is one of constant development. There is no such thing as learning everything and being ready. Games change, approaches change, and players change too. So learning, trying, making mistakes, and learning again is part of the journey,” emphasizes Yevhen Kasyanenko.

Why is it important to trust game design to professionals?

In game development, one miscalculated mechanic can eat up half the budget and delay the release by months. A professional team eliminates this risk from the very start. When you work with KISS Software, you get not just a “working game,” but a well-thought-out product that people want to play and that generates revenue. Here’s why it’s important:
