How to Make a Game: Step‑by‑Step for First Indies

This isn’t a “how to use Unity” tutorial.

This is for you if:

• You want to make your first commercial game (indie counts).
• You care about giving players a specific, repeatable experience (relaxation, tension, mastery, fear, etc.).
• You want strangers to buy and enjoy it, not just your friends.

The reality: there are thousands of games releasing every year across PC, consoles, and mobile. Simply “opening an engine and making something” is not enough any more.

The advantage: the foundations that separate forgettable games from the ones people talk about are the same as they’ve always been. Most beginners skip them. If you don’t, you already stand out.

Here’s a step‑by‑step way to make a game that’s actually worth playing.

Step 1: Decide the Experience and the Player

Before you think about engines, decide:

• Experience: How do you want players to feel while they play? Calm? On edge? Clever? Overpowered?
• Player: Who is this for?
  • Kids, teens, young adults, older players?
  • PC, console, or mobile?
  • Short sessions or long marathons?
  • What games do they already love? What do they hate?

You’re building a player persona: a simple snapshot of the person you’re designing for. For example:

“PC players in their 20s–30s who love deep strategy, have 45–60 minutes per session, and care more about systems than graphics.”

From here on, your core question is:
“How do I use this game to reliably give this player this experience?”

If this feels fuzzy, grab the free Game Dev Starter Kit. Which includes, a lightweight player profile template to define your persona.

Step 2: Explore Multiple Ways to Deliver That Experience

“I have an idea” is cheap. You want multiple candidates for how to deliver the same core feeling to that player.

Keep your persona in mind and sketch a few variations:

• Camera: side‑view, top‑down, isometric, first‑person.
• Structure: short runs vs campaigns; single level vs hub‑and‑spoke.
• Pace: turn‑based, real‑time, or a hybrid.
• Input: mouse‑heavy, controller‑heavy, touch‑friendly, etc.

You’re not hunting for ten random games. You’re searching for the best expression of your chosen experience for your chosen player.

Write each idea as:

“For [player], this version would feel more X and less Y because…”

Those tradeoffs will matter when you start testing.

Step 3: Prototype Fast and Cheap

Now you turn those ideas into playable experiments your persona can actually react to.

You prototype to answer:

• Which version of this idea is most fun for this player?
• What do they actually do from moment to moment?
• What feels clunky, confusing, or boring once it’s real?

Use the cheapest tools that can answer the question:

• Paper / boardgame prototypes: Use paper, coins, dice, and simple tokens to physically simulate the game at a table, playing through turns as a real session to validate decisions, pacing, and basic rules before writing any code.

• Digital prototypes: Once the table version shows promise, build a very rough in‑engine version: no art, no polish, just movement, timing, and basic interactions.

The loop here is short:

Prototype → let someone like your persona play → watch → change it.

You’ll keep doing versions of this all the way through development. Good games don’t come from one “perfect” idea; they come from a series of small and frequent validations that steadily shape the experience into something people actually enjoy.

If you’re not sure how to structure early tests, the Game Dev Starter Kit includes a simple prototype + playtesting checklist so you’re not just asking “Did you like it?” and hoping for useful feedback.

This is where you find your real value proposition: the specific behaviors and moments players actually enjoy.

Step 4: Lock the Core Loop and Constraints

Once one version clearly “wins” in playtests, you commit.

• Core loop:
  One clean description of what the player repeatedly does:

  “Explore → fight → collect → upgrade → push deeper.”

• Constraints:

  • Platforms you’ll support
  • Session length
  • Target scope (hours of content, number of levels / enemies / items)
  • Time, budget, and team size

Write these down. From here on, they’re your filter:

• Does this feature strengthen the core loop for this player?
• Does it fit within our constraints?
• If we add this, what are we cutting or delaying?

This is where you stop chasing every cool idea and start sculpting a shippable game.

Step 5: Move From Pre‑Production to Production on Purpose

For many teams, a vertical slice or strong demo is the last pre‑production gate: “We’ve proven the core loop, the look, the feel, and the technical approach.”

Production starts after that gate. At that point you stop asking “What game are we making?” and start executing: “We are making this game, to this quality bar, by this date.”

In production, your milestones are simpler:

• Alpha

  • All major systems are implemented.
  • You can play through the whole game end‑to‑end, even if ugly and unbalanced.

• Beta

  • Content complete (no new levels/systems).
  • Focus on bug‑fixing, tuning, UX and readability, performance.

• Release / Launch

  • Platform requirements met, last‑mile bugs fixed.
  • Only critical issues get changed.

Two key ideas for this phase:

1. Don’t drag pre‑production questions into production. If you’re still debating fundamental mechanics during “alpha,” you’re not in alpha, you’re still prototyping with a bloated codebase.

2. Make each production milestone prove something.

   • Alpha proves “the whole game exists.”
   • Beta proves “the game is stable enough to tune.”
   • Release proves “we’re willing to ship this to paying players.”

Vertical slice (if you do one) is the finish line of pre‑production. Alpha is the starting line of production. Treat that transition as a decision, not a slide, and your chances of finishing a real, commercial game go way up.

Step 6: Keep Prototyping Inside Production

Most beginners treat prototyping as something you do once at the start. That’s a mistake.

Inside production, keep a small, fast lane for experiments:

• Try new enemy types, abilities, or level ideas as tiny prototypes first.
• Use existing assets and systems to test variations quickly.
• Prototype UX changes (menus, HUD, onboarding) before rolling them across the whole game.

This preserves the muscle you built early: test small, decide fast, then commit. It’s how you avoid bloated feature lists that sounded good in meetings but feel bad to play.

Step 7: Test With Real Players, Not Just Your Team

Your teammate saying “it feels fine” is not market validation.

Throughout development:

1. Bring in testers who actually match your player persona.
2. Let them play with minimal explanation.
3. Watch what they do:
   • Where do they smile, lean in, or keep trying?
   • Where do they stall, get confused, or go quiet?

Afterward, ask a few focused questions:

• “When were you most into it?”
• “When did it drag or feel unclear?”
• “If this was on sale tomorrow, would you buy it?”

Compare what you see to the persona you defined in Step 1. The Game Dev Starter Kit’s player profile template is handy here: it lets you check “Are we still building for this person, or has the game drifted?”

Change the game based on patterns you see. Don’t “educate” players into liking it.

Step 8: Finish Something You’re Willing to Ship

You’re not trying to build the perfect game in your head. You’re trying to ship a real one.

Finishing means:

• The core experience you set out to deliver is consistently there.
• The most painful bugs and UX issues are fixed.
• The game runs reliably on your target platforms.
• You’re proud enough of it that you’d put it in front of strangers without apologizing every 30 seconds.

You can always improve post‑launch. But until you ship something, you haven’t actually “made a game.” You’ve just learned a lot about game development.

If you follow these steps, you’re not just “learning an engine.” You’re learning how to design for a real player, prove what works through prototypes and playtests, and then carry that discipline all the way to a finished, commercial‑ready game.

If you want help structuring your ideas, defining your player, and running your first prototypes and playtests, start with the free Game Dev Starter Kit. It’ll keep you from skipping the invisible work that actually makes games worth playing.

Wrapping It Up (and What to Do Next)

Making a commercial game isn’t about finding the perfect engine trick. It’s about doing the boring, powerful work: choosing a clear player and experience, prototyping and playtesting until something is genuinely fun, locking your core loop and constraints, then walking through production with simple, honest milestones until you ship.

If you want help turning this from “nice theory” into progress:

• Start with the free Game Dev Starter Kit to define your player, structure your first paper/digital prototypes, and run playtests that actually tell you what to fix.
• When you already have a game in motion and want outside eyes to sharpen the core experience, cut the noise, and build a realistic design + roadmap, that’s what our Game Design Offer is for.

FAQ: Making Your First Commercial Game

Do I need to pick an engine before I start?
No. Start with the player, experience, and paper/tabletop prototypes. Once you’ve found a core loop that works, then lock in an engine based on your needs (platform, visuals, performance, tools).

Can I make a commercial game solo?
Yes, but you still have to cover the same jobs: design, programming, art, QA, and production. Solo just means you’re wearing multiple hats. Be ruthless about scope or you’ll never reach the finish line.

How long does it take to make a first commercial game?
It depends on scope, but for a solo or tiny team, plan on 6–24 months for something small but polished. If you think you’ll “knock it out in a couple of weekends,” your scope is probably lying to you.

What’s the difference between a prototype and the real game?
Prototypes exist to answer questions: “Is this loop fun for this player?” They’re cheap, disposable, and often ugly. The real game is what you build after those questions are answered: committed art, code, content, and structure around the winning behaviors.

Do I really need a vertical slice?
If you want funding, a strong portfolio piece, or to promote/exhibit early, yes: a vertical slice is almost mandatory. It shows a small part of the game at near‑final quality so people can trust what you’re building.
For a tiny, fully self‑funded project, you might skip a formal slice, but you still need a clear internal target for what “final quality” looks and feels like before you build the whole game.

When should I start thinking about marketing?
It depends on who’s doing the marketing and what path you’re taking:

• If you are doing it yourself, start thinking about it once your core loop is fun and you know who the game is for.
• If you’ll use a publisher/marketer, they’ll bring their own approach, but they’ll still want a clear target player and a convincing build.

There are many ways to market a game, and this site doesn’t pretend to be a marketing bible. Our bias is simple:

1. Build a genuinely strong, focused game people want to talk about.
2. Then layer formal marketing on top (publisher, PR, creators, ads, etc.) instead of using marketing to prop up a weak experience.

What’s the biggest mistake first‑time devs make?
Skipping prototyping and playtesting.

Most beginners jump straight into making a “demo” or mini‑vertical slice, spend months polishing it, and only then discover the core game isn’t actually that fun or clear. Then they burn even more months trying to fix a broken foundation.

Do it in this order instead:

1. Prototype and playtest until you find something that’s genuinely engaging.
2. Only then start building a demo, slice, or full production around that core.

You’ll move faster, waste less time, and avoid rebuilding big chunks of the game over and over.

How do I know when my game is “good enough” to ship?

It’s case by case, but you’re usually deciding between three constraints:

• Money / time: your budget or schedule can’t stretch further.
• Content / story: you’ve hit the minimum amount of game or story you’re comfortable putting your name on.
• Player experience: people who match your target player can reliably get to the experience you promised (fun, tension, calm, etc.) without you standing there explaining everything.

Some devs bootstrap by releasing on Early Access, then improving over time. Others aim for a more traditional “1.0” once they hit a clear content and quality bar.

Simple rule of thumb:

• Players in your target persona can play, understand, and enjoy the core loop on their own.
• Crashes and game‑breaking bugs are rare.
• The things you still want to add are “nice to have,” not “this game is broken without it.”

When that’s true, it’s usually better to ship, learn, and make the next game better than to hold this one hostage to an ever‑moving idea of perfect.
