Best AI Game Generator to Generate Assets and Entire Games

The power of AI is now taking the game development world by storm. However, with so many companies making big promises, I got hands-on and narrowed down 10 workable solutions, so you can find the best AI game generator for you.

10 Best AI Game Generator Platforms

From basic asset generators to full game development platforms, these 10 AI game generators have something to offer developers of all sizes and skill levels:

1. Promethean AI – Best 3D Environment Generator

It’s important to have a world for your game to live in and Promethean AI is at the cutting edge of generating detailed 3D environments using AI.

From rich fantasy lands to detailed cities or building interiors, you can speed up the development process with just a few simple prompts.

It has the power to generate entire game worlds just from text! However, if you have existing concept art, landscape images, or specific objects, these can also be quickly morphed into vibrant environments and assets.

It’s as easy as choosing different styles and using Promethean’s additional tools to refine the results to your liking.

What’s more, your finished work can be exported to all popular 3D editors, including Unreal, 3DS Max, and Unity.

You can test it for free with limited free credits. If you like it, upgrading to premium costs from $29.99/mo or $239.88/yr, representing 33% off.

Promethean AI Key Features:

• Text and image to 3D environment
• You combine styles and prompts with existing images
• Supports single assets
• Huge library of existing models

2. Rosebud AI – Fastest AI Game Generator

If you want to build a simple game fast, that’s playable right away, Rosebud AI is an impressive all-in-one solution.

Through AI prompting, it takes your descriptive concept of a game and generates the assets. Furthermore, it will create the underlying code to the point where you can publish and play it on the platform itself.

While it’s most suitable for basic games, there is lots of room for refinement, with tools for character and asset customization, intelligent NPCs, and AI-assisted coding for developers who can already write code themselves.

The ability to pre-play and troubleshoot with the help of AI is a huge plus.

The free forever plan is useful for familiarizing yourself with the platform but limits prompts and doesn’t support long-term memory. You can get a premium plan at just $12.99/mo to unlock all features.

Rosebud AI Key Features:

• Prompt, publish, and play platform
• Custom coding with AI-assistance
• Asset and environment generations
• Share publicly or export your game privately

3. Meshy AI – Best 3D Model Generator

If you’re developing a 3D game, modeling is a costly and time-consuming process. Not with Meshy AI. Now in its 4th release, this powerful web-based platform can quickly create 3D game assets based on your concept art and object images, allowing you to streamline the entire process.

Simply upload each object or character, preferably front facing, choose the AI model, and it will render in 3D in as fast as a minute. It also supports text-to-image prompts, requiring no original art at all!

Once generated, it’s easy to customize the hard surface and organic models. You can use different textures, mesh settings, colors, and shading. You can even animate humanoid characters.

It’s already a go-to for indie studios and game developers who want to use AI to boost their existing skills.

Leonardo stands out the most for its optimization capabilities. By analyzing the assets’ geometry, materials, textures, and other properties, the AI identifies areas where performance can be improved without sacrificing visual quality.

It also generates multiple versions of an asset with varying levels of detail, allowing game engines to use lower-detailed versions of the asset when it’s further away from the player.

9. InWorld – Best for Established Studios

InWorld is one of the most comprehensive AI game development platforms for indie developers and large developers alike.

Unlike some of the AI game generators on this list, InWorld is not just an asset or art generator. It can also incorporate AI within your game’s world. These pre-built modules, called AI Primitives, cover a range of use cases, including pathfinding, decision-making, and character behavior generation.

Characters interact with players in a natural and engaging way and are trained to recognize player behavior and adjust their own behavior accordingly. This creates a more immersive and realistic gaming experience.

Of course, character creation itself is part of the platform and you get lots of character trait tags and mood sliders to bring them to life, before using the voice studio to generate realistic audio dialogue.

Its Narrative Graph tool lets you build non-linear plots and visualize stories in an efficient manner.

All your assets are hosted in one dashboard, which streamlines the team’s collaboration and workflow.

Its toolset even helps optimize game design based on player behavior with AI-powered split testing. This allows you to refine your game through internal testing and BETA releases.
