Question: Is there a game builder that allows for easy world creation and customization with AI assistance?

If you want a game builder that lets you create a world and populate it with characters and other elements with AI help, Tempest AI could be the ticket. The platform lets you build a game without any programming with a drag-and-drop world builder, an AI assistant, and tools for creating characters and story. The AI can generate characters with motivations and phobias, goals that can be changed, and stories that adapt to player choices, so it's a good option for game developers.

Another option is Inworld, which offers an AI engine to help developers create realistic AI agents and a dynamic game world. The platform includes a real-time AI engine, content creation studio and tools for character creation and dialogue management. It's designed to keep players engaged and retain them, with a narrative graph framework for interactive storytelling and a variety of tools to manage creative work.

For those who need to create 3D models as fast as possible, IzanamiAI offers an AI-powered virtual world design tool that can generate 3D models, characters and environments from text prompts and images. It offers instant 3D creation, easy animation and automatic retopology, so it's good for developers and designers who want to quickly bring their virtual world to life.

Last, Dreamlab is a game engine that lets developers build multiplayer games fast with modern web technology. It has real-time multiplayer abilities and uses AI to generate game assets like levels and characters. The platform is built for web-based development and comes with an integrated AI coding assistant, so it's a good option for those who want to concentrate on game design rather than creating assets.
