Game development platforms are digital marketplaces and engines where indie creators build, publish, and sell their games while the platform takes a cut of revenue.
Think of them as landlords who provide the tools and storefronts, but you’ve got to pay rent through commission fees that range anywhere from 0% to a brutal 70% depending on where you set up shop.
Why Your Platform Choice Actually Matters
You can make the best turn-based RPG in the world, but if you’re losing half your revenue to platform fees, you’re working for someone else. I’ve watched developers pick platforms based on “community” or “exposure” without doing the math first. Big mistake.
Here’s what you’re actually paying:
Steam takes 30% of everything you make. Yeah, it’s expensive, but you get access to 120 million active users who actually spend money on games. The visibility tools are solid, the infrastructure works, and refunds don’t destroy you like on some other platforms.
Itch.io lets you set your own revenue split. You can give them 0% if you want, though most developers do 10% because it feels less scummy. The catch? Way fewer eyeballs. You’re trading traffic for better margins, which works great if you already have an audience or you’re making weird experimental stuff that Steam users wouldn’t touch.
Roblox is where things get complicated and kind of predatory if we’re being honest. The platform runs on Robux, their fake money that you buy with real money. When players spend Robux in your game, Roblox keeps about 30% right off the top. But wait, there’s more. When you want to cash out your Robux earnings into actual dollars, they hit you with another conversion fee through their DevEx program. You need 30,000 Robux minimum to even withdraw, and the exchange rate means you’re getting roughly $0.0035 per Robux.
So if a player spends $10 on your game, you’re lucky to see $2.50 after Roblox takes their cut twice. That’s a 75% platform tax when you account for the whole chain. You should probably check a Robux tax calculator before you commit to building there because the math gets brutal fast.
The Real Costs Nobody Talks About
Beyond the percentage cuts, you’ve got hidden costs that add up:
Steam charges $100 per game just to list it. Sounds small until you’re an indie studio releasing three games a year. Itch.io has zero upfront costs. Roblox is free to publish on but you’ll spend money on Robux yourself for testing and assets unless you want to grind like a player.
Then there’s the payment processing. Most platforms eat this cost, but some pass it along. Credit card companies take 2-3% of every transaction, and somebody’s paying for that.
When Free Isn’t Actually Free
Roblox’s model attracts millions of young developers because there’s no barrier to entry. You can start building today with zero investment. And sure, some creators make millions. But most people creating games on Roblox make nothing because the platform is flooded with content and the discovery algorithm favors games that already have traction.
Steam’s $100 fee actually filters out garbage. It’s high enough that people think twice before uploading broken meme games, but low enough that serious indie developers can afford it.
Itch.io sits in the middle. Free to publish, but you really need your own marketing because their discovery is basically nonexistent compared to Steam.
The Platform That Makes Sense for You
If you’re making a traditional turn-based RPG with pixel art and you want to reach PC gamers who actually pay for games, Steam is still king. The 30% hurts but the audience is there.
If your game is experimental or you’ve built a following on social media already, Itch.io gives you control and better margins. You can run sales without asking permission and keep the bulk of your money.
If you’re targeting kids or you want to make a multiplayer experience where the platform handles servers and social features, Roblox works. Just know you’re working in their ecosystem with their rules and their economics. The creator economy is real, but the take rate is rough and you need massive scale to make real money.
Bottom line: Do the math on your expected sales before you commit. A platform with lower fees but no traffic is worse than a platform with high fees and guaranteed visibility.
