How to Make a Game Like Roblox with AI (Step by Step)

People search "make a game like Roblox" expecting one of two things: a tool that recreates Roblox the platform, or a way to build the kind of game they play inside Roblox. The first is a trap. The second is very achievable, and it is what this guide covers.

Roblox is not a single game. It is a platform that hosts millions of them. The thing you actually love is probably one genre: an obby (an obstacle course), a simulator (click to earn, buy upgrades, repeat), a tycoon (build a business on a plot), a sandbox build mode, or a social hangout. Cloning the whole platform is the wrong goal for one person. Recreating one of those experiences as a game you own is the right one.

This is a build-it-with-AI guide. We will break down the mechanics that make Roblox games work, then build one step by step in Summer Engine, the AI game engine compatible with Godot 4. The output is a standard Godot project you can edit, expand, and ship anywhere, including places Roblox will never let you go.

What Actually Makes a Roblox Game Work

Almost every popular Roblox experience is some combination of these systems:

• A tight core loop. Do a thing, get a reward, spend the reward to do the thing faster or bigger. Simulators are the purest example: collect, sell, buy an upgrade, collect faster.
• A persistent number that goes up. Coins, gems, steps, pets, plot size. The hook is watching a counter climb and unlocking the next tier.
• Lightweight 3D characters and physics. Roblox avatars are simple capsules with chunky animations and forgiving physics. That is a feature, not a limitation, because it keeps the feel snappy.
• Social presence. Other players in the same world, a leaderboard, a chat. Even single-player-feeling games show you where everyone ranks.
• Instant replayability. Short runs, fast respawns, no long load.

You do not need all of these for your first game. You need the core loop and the number that goes up. Everything else layers on after the loop is fun.

Step 1: Pick the One Roblox Genre You Are Recreating

Decide which experience you are building before you open the engine. Each maps to a different starting template, so the AI begins from working systems instead of a blank scene.

Roblox genre	Core loop	Best Summer template
Obby (obstacle course)	Jump, dodge, reach checkpoint, repeat	Platformer
Simulator	Tap or collect, sell, buy upgrade, collect faster	Simulation
Tycoon	Earn money, buy droppers and machines, expand a plot	Simulation
Sandbox build mode	Place blocks or parts, save your creation	Survival (voxel and building sandboxes)
Survival world	Gather, craft, build a base, fend off threats	Survival

For this walkthrough we will build a simulator, the clearest example of the Roblox loop and the easiest to make fun fast. If you would rather build an obby, follow the same steps from the platformer template and ask for checkpoints and a respawn system instead of a sell-and-upgrade economy.

Step 2: Open a Template and Describe the Loop

Create a new project, pick the Simulation category, and describe your game. The AI builds what you say, not a generic default, so the prompt matters. Here is a starting prompt for a pet-collecting simulator, the most common Roblox simulator format:

Make a 3D simulator. The player walks around a small floating island and clicks glowing orbs to collect coins. A coins counter shows at the top of the screen. There is a shop with three upgrades: a bigger collection radius, more coins per orb, and faster movement speed. Buying an upgrade spends coins. Simple low-poly style, bright colors, third-person camera. Orbs respawn a few seconds after being collected.

From that, the AI assembles a real project:

1. A third-person player controller with walk and a follow camera
2. A floating island scene with collectible orbs placed around it
3. A coins system that increments on pickup and shows a UI counter
4. A shop UI with three upgrades, each with a cost and an effect
5. Upgrade logic that spends coins and changes the radius, coin value, or speed
6. An orb respawn timer so the loop never runs dry

Hit play and you have a loop: collect, save up, buy an upgrade, collect faster. That is the Roblox simulator in its purest form, running as a Godot game.

Step 3: Iterate the Loop Until the Number Feels Good

A simulator lives or dies on pacing. If upgrades are too cheap, the fun ends in two minutes. Too expensive, and players quit before the first reward. You tune this through conversation, and you tune it while playing, not by editing config blindly.

Try refinements like:

"The first upgrade should cost 50 coins, the second 250, the third 1000. Make each tier feel like a real milestone."

"Add a rebirth button. When the player has 5000 coins, they can reset their coins but permanently double their coin gain. Show a rebirth count next to the coin counter."

"Add a second area behind a locked gate that costs 10000 coins. The orbs there are worth 10x but the area is more dangerous."

That rebirth and prestige loop is exactly what keeps Roblox simulators sticky for months. The AI edits the existing economy scripts and UI rather than regenerating the game, so your tuning accumulates like any normal development session. Every value you are adjusting is a real export variable in a real GDScript file, so you can drag a slider in the inspector or keep talking to the AI, and both edit the same project.

Step 4: Add the Social Layer (Leaderboard and Multiplayer)

Roblox feels social even when you play alone, because of the leaderboard and the presence of other players. Add the leaderboard first, it is the easy win:

"Add a leaderboard panel that ranks players by total coins. For now, fill it with placeholder bot scores so the player has something to climb past."

Then real multiplayer, once the single-player loop is genuinely fun:

"Make this multiplayer. Other players appear on the same island. Each player has their own coins and upgrades. The leaderboard shows everyone's live coin totals."

Godot has built-in high-level networking, and Summer Engine scaffolds a host-authoritative setup: the host owns the shared world, clients send input, and the host validates and broadcasts the result. This is the right architecture for a Roblox-style game and the one that resists cheating.

Be honest with yourself: multiplayer is meaningfully harder than single-player in every engine ever made. Ship the single-player loop first, add players to the same world second. For the networking patterns in depth, see our guide on making multiplayer games with AI.

Step 5: Switch to the Editor When You Want Precision

At any point, stop chatting and work directly in the Godot editor. Everything the AI built is standard Godot: scenes, scripts, and resources, nothing obfuscated. You can model or import your own low-poly parts to replace placeholder shapes, tune coin values and upgrade costs in the inspector, write GDScript for a mechanic the AI did not nail, or place collectibles and gates by hand for a deliberate pace.

This is the line between an AI game maker and an AI game engine. A maker hands you a finished thing. An engine hands you a project you can open, inspect, and change at every level, with AI as one of the tools inside it.

Step 6: Export and Ship It Anywhere

This is the part Roblox cannot do. Your game is a standard Godot project, so you export it like any Godot game.

• Desktop (Steam, itch.io): File > Export > Windows / macOS / Linux, then upload the build.
• Web: File > Export > HTML5, then host the files or share a link. This is the closest analog to the Roblox click-and-play experience, and it is yours.
• Mobile: File > Export > Android / iOS, then submit to the store.

Export works because Summer Engine is compatible with Godot 4. Standard process, standard output, no platform lock.

Honest Comparison: Roblox Studio vs This Approach

Roblox Studio is genuinely good at what it does, and for some goals it is the right tool. Here is the straight version of the trade-off.

	Roblox Studio	Summer Engine
Where your game runs	Only inside Roblox	Steam, itch.io, web, mobile, anywhere
Language	Luau	GDScript (Godot 4)
Who owns the game	Lives in Roblox's ecosystem	You own the project outright
Built-in player audience	Huge, ready-made discovery	None, you bring your own players
Revenue split	Roblox takes a large cut	Keep your platform's terms (e.g. Steam's standard split)
Moderation	Roblox's rules apply	Your call
Multiplayer	Built in, server-hosted by Roblox	Godot networking, you host or use a backend
AI building	Studio has AI assist	AI builds the whole project in conversation

If your only goal is to reach the existing Roblox audience tomorrow, Roblox Studio is the pragmatic choice, and that is a real advantage worth naming. If you want to own your game, ship it on Steam, keep more of the revenue, and answer to no single platform's rules, build it standalone. The skills transfer either way: the loop-and-economy thinking that makes a good simulator on Roblox makes a good one anywhere.

Free vs Paid: What This Actually Costs

Summer Engine is free to download, and you can build and export a complete game on the free tier, which includes a usage allowance for the AI that is enough to scaffold and iterate on a first project. Heavier, sustained use (long sessions, large projects, the more capable models) is where a paid plan makes sense, and the current limits are on the pricing page. The engine, the editor, the export, and the project are yours on any plan, because the output is an ordinary Godot project. There is no per-game cut and no platform tax on what you ship, which is the structural difference from Roblox.

Five Roblox-Style Prompts to Try

Pet-collecting simulator

Make a 3D simulator where I collect coins by clicking orbs, buy upgrades for radius and coin value, and unlock pets that auto-collect for me. Add a rebirth system that doubles gains. Bright low-poly style.

Obby (obstacle course)

Build a 3D obstacle course. The player runs and jumps across floating platforms with moving parts, spinning beams, and disappearing tiles. Checkpoints save progress, and falling respawns me at the last checkpoint. Stage counter in the corner.

Tycoon

Create a tycoon on a small plot. I buy droppers that spawn money on a conveyor, the money collects at the end, and I reinvest to buy bigger droppers and expand the factory. Show my cash and let me purchase new machines from buttons on the plot.

Sandbox build mode

Make a voxel building sandbox. I can place and break blocks of different colors to build whatever I want, with a free-flying camera and save and load so my creation persists. Simple block textures, snapping placement.

Survival hangout

Build a small open world where players gather wood and stone, craft tools, and build a base. Add a day and night cycle where it gets more dangerous at night. Third-person, low-poly, designed for several players in the same world.

Start Building

Pick the one Roblox genre you actually love, start from the matching template, and describe the loop. You will be playing a working version in minutes, and unlike a Roblox experience, you will own every file.
