| Browser, no code | A first game this weekend, shared as a link | Rosebud AI (or Bolt.new) | Free plan |
| Roblox | Players already on the platform | Roblox Assistant, then Claude Code, Cursor, Codex or Antigravity through Studio MCP | Studio is free; Assistant's docs list no price |

Step 2: Set up the AI for your path
Browser with Rosebud AI
Sign up for the Free plan, which starts with 8,000 credits and refills weekly in eligible regions. An edit with the default AI, Rosie, costs about 2,000 credits, and an edit with a premium model about 20,000. Images and sprite animations cost 200–2,000 credits, sounds about 1,000 and 3D models about 1,000. Rosebud AI pricing (opens in a new tab)
Roblox
Open Assistant in Studio. For an external agent, go to Assistant → … → Manage MCP Servers → Enable Studio as MCP server, then quick-connect Claude Code, Cursor, Codex CLI, Antigravity, Claude Desktop, Gemini CLI or VS Code. Roblox MCP docs (opens in a new tab) Full walkthrough: best AI for Roblox scripting.
Unity
Use Unity 6 or later. Install Unity's official plugin into Claude Code or Codex (it bundles Unity skills, the CLI and the MCP server), or connect another agent through the MCP server via the Unity CLI. Unity's AI tools (unity.com) (opens in a new tab) Details: best AI for Unity.
Godot
Create a project, open the folder in your coding agent and keep Godot open beside it. For editor control and AI playtesting, add an MCP server such as Godot MCP Studio (Lite is free; Pro is €39 one-time until 4 November 2026, then €59). Godot MCP Studio editions and pricing (opens in a new tab) Godot MCP Studio homepage (pricing) (opens in a new tab) Details: best AI for Godot.
Step 3: Write a one-paragraph game brief
Before any prompt, write down: the core mechanic (one verb, such as jump, dodge or collect), the win and lose conditions, the camera (top-down, side or 3D), and the controls. Keep it to one screen. A small, finished game teaches you more than a big, broken one.
Step 4: Ask for a plan, then build one feature at a time
- “Read the brief and propose a plan in five or fewer steps. Don't write code yet.” Roblox Assistant has a Planning Mode that only runs when you click Build. Roblox Assistant docs (opens in a new tab)
- “Implement step 1 only.”
- Playtest.
- Paste any error back to the AI, or let an MCP-connected agent read the console and start the playtest itself.
- Commit to Git (or duplicate your Roblox place) before the next step.
Step 5: Add art and sound
Only once the game is fun with placeholder shapes. Roblox Assistant can generate meshes, materials and procedural models (up to 50 procedural models per rolling 24 hours). Roblox Assistant docs (opens in a new tab) Rosebud generates sprites, sounds, 3D models and skyboxes on credits. Rosebud AI pricing (opens in a new tab) For other engines, use dedicated generators (table below).
AI asset generators for games
| Tool | Makes | Pricing (checked 2026-10-17) |
|---|---|---|
| Meshy (opens in a new tab) | 3D models (text/image → 3D, texturing, rigging) | Free 100 credits/mo (CC BY 4.0, attribution) · Pro $20 (1,000 credits) · $40 · $100 source (opens in a new tab) |
| Tripo AI (opens in a new tab) | 3D models (image/text → 3D, retopology) | Free 200 credits/mo (~13 models, public, non-commercial) · Pro $20 (3,000) · Max $90 source (opens in a new tab) |
| Scenario (opens in a new tab) | 2D art, sprites, textures, video and 3D in a consistent style | Free 50 credits/day (personal/eval use) · $15 · $45 · $75 per month source (opens in a new tab) |
| PixelLab (opens in a new tab) | Pixel-art characters, animations, tilesets | Free trial 40 generations then 5/day · $12 · $24 · $50 per month (third-party summary; verify) source (opens in a new tab) |
| ElevenLabs Sound Effects (opens in a new tab) | Sound effects from text | Free 10,000 credits/mo (~50 SFX, non-commercial, attribution) · paid from $6/mo source (opens in a new tab) |
| Suno (opens in a new tab) | Music and soundtracks | Free 50 credits/day (~10 songs, non-commercial) · paid plan needed for commercial use (price: see site) source (opens in a new tab) |
| Blender (opens in a new tab) | Free 3D editor to clean up, rig and export AI meshes | Free and open source source (opens in a new tab) |
Free tiers often restrict commercial use (Tripo, Scenario, ElevenLabs and Suno free outputs are non-commercial; Meshy's free tier is CC BY 4.0, so you must give attribution). Read the licence before shipping.
Step 6: Check rights before you publish
- Rosebud: full commercial rights start on 10x Dev. Pro and up can download code and export a Windows build you can publish on Steam. Rosebud AI pricing (opens in a new tab)
- Unity: assets from the in-editor assistant carry AI-generated metadata, and you're responsible for app-store declarations and usage rights. Unity's AI tools (unity.com) (opens in a new tab)
- Godot: you own your game. Include Godot's licence notice when you ship the engine binary. Godot Engine licence (opens in a new tab)
- Asset generators: several free tiers are non-commercial. Read each licence.
Step 7: Share it and keep going
Browser games share as a link, and Roblox games publish from Studio. For Godot and Unity, export a build. Then add one feature per session. When your AI plan runs out mid-project, see hit my usage limit. Keeping a free backup from another company means you don't have to stop.
