How to Create a Video Game Character

A video game character has usually been through more before launch than they'll ever face in gameplay. What comes out the other side—the version players love and adore—rarely looks like what anyone planned at the start.

Here’s your ten steps, in the order they should happen.

Step 1: Start With the Character's Role

A playable protagonist, a recurring NPC, a one-scene vendor, a villain with an arc? Establishing the role early is where video game character design begins — it determines how much resource investment they warrant, how complex their voice needs to be, how much personality they need to carry.

Art, audio, and narrative all build on top of role definition. Get it wrong with a side character and you're suddenly recasting, re-recording, and reworking animations. All mid-production.

Ask three questions at this stage: 

• What does this character do for the player?
• How often will the player interact with them?
• What would the game lose if this character wasn't in it?

Answer all three clearly and you have enough to move to the next step.

Step 2: Build the Character Core

Concept art, dialogue, and voice casting need something to anchor to. That something is the character's internal logic — whether they go quiet or loud when things go sideways. Most of it traces back to one question: what does this character actually want? 

When you know that, the behavior follows. The backstory can be two sentences — as long as those two sentences explain why they do what they do.

Step 3: Visual Design That Supports Gameplay

A lot of what makes a character visually work has nothing to do with detail. It’s how they read from a distance, mid-action, on a small screen. A strong silhouette tells the player who they're looking at without needing a close-up.

This is one of the more practical constraints in how to make a video game character that functions in-engine. Ask early: would you recognize this character from their outline alone?

Visual design should also reflect what you built in Step 2. A cautious character and an aggressive one shouldn't carry themselves the same way — bring that difference in design before it's in the animation.

Step 4: From Concept Art to 3D

Here’s one of the less glamorous parts of making a video game character: concept art and 3D modeling operate in different realities. The model has to live inside an engine, with polygon limits, unpredictable lighting, camera angles nobody sketched.

Cleaner reference art means fewer questions mid-build. Turnarounds—front, side, back—are more useful than a single polished hero shot. Modelers need to know what the character looks like from angles you won’t ever frame a poster around.

Step 5: Animation & Performance Planning

Put animators and writers in the same room and make them work from the same character notes. How a character walks when they're confident versus when they're afraid is a character decision that animation executes. 

Idle cycles and transition animations get underestimated here. Players spend a lot of time watching characters do nothing in particular: wait, stand, look around. That's not a moment most teams optimize for, especially when there's a trailer to fill with combat and cutscenes.

Step 6: Writing Dialogue That Sounds Like a Real Person

Nobody plays dialogue in order. Lines get triggered early, skipped, heard out of context. If a line only works after three others, it's likely going to break. Write every line to stand alone — that's the real job when you're figuring out how to create video game characters that feel consistent.

Make sure you catch performance problems in the script, not after hearing the recorded version. Read it out loud. If you stumble, the actor will too.
Dialogue barks are easy to underwrite. If they feel generic or mismatched to the character you built, players will notice before they can articulate why.

Step 7: Casting the Voice

Don't cast from a resume, cast from the character. Emotional range, speech patterns, behavioral quirks — those should drive the decision.

Before you hear the first audition, write down what you're listening for. Pitch, pacing, accent, how the voice changes under pressure. That's the voice profile. It keeps the room honest.

The best results come from actors who understand the character. Give the director enough to make that possible.

Step 8: Creating an AI Voice for Your Character

Hundreds of lines, multiple languages, dialogue that needs updating months after launch. If you want to create your own video game character with a fully realized voice, at some point the recording pipeline wasn't designed for any of that. Ethical AI was.

The original actor should know how their voice is being used and have agreed to it. When platforms skip that conversation entirely, it creates problems — for productions, for actors, and for anyone trying to use AI voice as a serious tool.

When AI works best: 

• NPC lines at scale
• Localization
• Iterative updates
• Voice matching for legacy characters

Step 9: Implementation in the Game

File formats, sample rates, naming conventions — nobody thinks about these until something breaks mid-build with no clear reason why. Set the technical specs before recording starts.

Dialogue triggers need the same attention. A line that plays at the wrong moment or fires over another one can break the flow. When you make your own video game character, the voice system has to reflect the same logic as the character design.

Before QA, audio and narrative should have agreed on:

• Consistent file formats across all voice assets
• Naming conventions tied to dialogue states
• Trigger logic reviewed by both teams

Step 10: QA for Character Voice

Two categories of problem show up in voice QA. Technical: lines firing late, overlapping, missing. And consistency: the character sounds slightly off in ways that are harder to trace.

Voice consistency breaks quietly — when sessions were recorded too far apart, when different directors gave conflicting notes, or when AI-generated lines weren't matched carefully enough to the original performance.

Both categories need dedicated passes. Technical issues have clear fixes. Consistency problems require someone who knows the character well enough to hear when something is wrong.

Final Thoughts

The process of making a video game character is long, and most of it is invisible to the player, which must be the point. When it works, nobody notices the pipeline — they just believe in the person on screen. That's the standard worth building toward.

The same standard applies to AI voice — the technology capable enough to be a real production tool. It just has to be treated with the same seriousness as everything else in this guide: consent, rights, quality. Exactly what Respeecher has worked from since the beginning.
