AI art is fast. It’s cheap. And when you’re 72 coffees deep into a dev sprint, using AI to generate key art can sound like a smart shortcut to tick “make game marketing art” off your to-do list.
But when it comes to your key art, especially yourSteam capsule, cutting corners here can quietly sabotage your visibility, credibility, and conversion rate.
We share data on why “good enough” isn’t enough, and what devs should consider before going full-AI on their most visible marketing asset (and how to get more wishlists).
Why Key Art Is Critical for Game Marketing
Your capsule is the first, and maybe only, thing a potential player sees, and if it doesn’t land, they don’t click. As a result, you lose the wishlist, the sale, the player.
Graffiti Games reported a 150% increase in Steam wishlists after refreshing their key art. → GDC 2021 presentation
Lab Cave’s redesign of store assets led to a 43% improvement in conversion rates, with further enhancements bringing an additional 14.2% increase. → SplitMetrics
Your game’s capsule art is your box cover, your thumbnail, your storefront. On overcrowded platforms like Steam or Epic, it’s what gets you clicked, or ignored.
The brilliant How to Market a Game says: “You need a professionally made capsule. No, you can’t make it yourself. Hire an artist. They are worth it.”

Can AI-Generated Key Art Compete?
AI can create some cool stuff, and we’re not pretending otherwise. Lighting, brushwork, composition? All convincing at a glance.
But “good enough” isn’t good enough when it comes to actually selling your game.
Steam capsules, where images are small and need clear, readable silhouettes at a glance. AI tends to overcomplicate, which muddies the message.
Promotional banners, which need a consistent visual style across sizes and platforms. AI-generated pieces often clash in colour, composition, or tone when used side by side.
Trailers and thumbnails, where the art has to match your game’s narrative and vibe. AI lacks the context to reflect your story or emotional beats authentically.
How to Spot the Common Mistakes in AI Art
Despite looking impressive at a glance, AI-generated visuals often fall apart in these areas:
Detail Collapses at Thumbnail Scale Steam capsules are tiny. If your characters or silhouettes blur into a messy shape, you’re toast. AI doesn’t optimise for clarity at small scale.
Anatomy and Structure Break on Inspection Ever spotted those famous “eight-fingered hands” or lopsided weapons? AI can’t understand anatomy – it just mimics the look. Bad anatomy kills trust.
Hard-Surface & Symmetry Failures Mechs, architecture, weapons: AI often melts them into surreal chaos. Symmetry becomes warped. Hard lines turn squishy.
Visual Noise and Style Clashes AI art often “collages” from datasets – great for moodboards, but terrible for consistency. You’ll spot:
Inconsistent lighting sources
Jumbled perspectives
Surreal background elements
Repetition in textures or shapes
Reese – one of our art directors: “Try asking AI for a clean mechanical suit or vehicle. You’ll end up with melted metal soup and cables growing in places cables shouldn’t grow.”
And even if the tech improves, AI can’t understand what matters most: your game’s soul, tone, or emotional payoff. There’s a Zero feedback loop – no way to evolve the art to sell your game.
Ludmila – MLC concept artist: “Giving your project a new feel, a new smell, a new visual, a new world comes from a unique mind. AI is helpful, yes, but it is not unique.”
Why Real Artists Build Better Game Capsule Art
Custom key art created by professional artists doesn’t just look better, it performs better. Engaging with experienced artists brings a level of intentionality and refinement that AI currently cannot replicate.
Artists capture genre, tone, and narrative
Their work aligns with gameplay and brand identity
It reads well at all scales and platforms
The ability to say: “This doesn’t work, here’s why and what would work better.”
Real artists can work with you. They can respond to feedback, troubleshoot composition issues, to develop visuals that are consistent and work across your entire pipeline.
Millie – MLC concept artist “Working with a real artist means you can really build a one-on-one relationship… you can challenge and give feedback too, make small adjustments here and there, and work to the client’s needs.”
What’s the Real Cost of AI Key Art?
AI-generated key art might save time in the short term, but it can come with serious downstream issues:
Lower click-through rates AI art often lacks visual focus, especially when shrunk for capsules. Players don’t engage if they can’t quickly parse what they’re looking at.
Anatomical and compositional dissonance Warped characters, messy silhouettes, mismatched lighting, even if players can’t name what’s wrong, they feel it.
Mismatch with gameplay If the art doesn’t match your actual tone or mechanics, players won’t trust what they’re seeing or worse, they’ll bounce.
Breaks player trust If your capsule looks AI-generated, players may ask: “What else was made with AI?” Even if they can’t explain it, players feel when something’s off. Consequently, they move on without a second thought.
Inconsistent branding Using AI across assets can result in a patchwork visual identity. This hurts your game’s cohesion and professionalism.
Weakens pitches to publishers or partners Polished presentation matters. If your pitch includes placeholder-y or AI-looking art, it can send the message that the team isn’t ready for market, even if the game is solid.
Let’s say your current capsule converts 1 in 100 users. If a professional redesign brings that to 1 in 70, that’s a 43% improvement in game sales.
For a £20 game, that could mean thousands in additional revenue over time, especially when multiplied by Steam event traffic or a front-page feature.
Commissioning great key art isn’t free, but it is accessible. At MLC Studio, custom capsule art typically ranges from £1.5k–£3k, depending on scope and complexity.
It’s a strategic investment that can pay for itself many times over.
Ludmila – MLC game artist “In my opinion, developers can’t see the real potential their work could have if it looked less like ‘everything else’ and more like ‘something unique.’”
The risk isn’t that players will know it’s AI. The risk is that it looks generic. Forgettable. Easy to scroll past.
Should You Use AI for Art?
To be clear: AI isn’t useless. It’s just a tool, and like any tool, it depends on how (and when) you use it.
Potential uses for AI in the early stages:
Generating mood boards or composition ideas.
Sparking ideas when you’re creatively blocked.
Quickly exploring variations but not final concepts.
AI can assist in the exploratory phase, however, it’s not a replacement for artistic instinct, problem-solving, or collaborative iteration.
Don’t rely on AI for:
Steam capsule art
Storefront visuals
Publisher pitch materials
Anything that needs to build trust or sell your game
Great games deserve visuals that do more than “look fine if you don’t zoom in.”
Reese – MLC art director “It’s great at creating a base image to be built from and can assist in making awesome colours and shapes. The problem lies in making something truly unique”
