Roblox Launches AI-Powered Mobile Game Creator, Starting with Public Beta in New Zealand

Summary

Roblox announced 'Build,' a new AI-powered tool that allows users to create games directly from text prompts on their mobile devices. The feature will initially launch in public alpha on July 28th in New Zealand for users aged 9 and older, with published games playable globally by users 16+. Build handles gameplay mechanics, environments, characters, visuals, sound, and more by combining Roblox's proprietary AI models with open-source solutions. The company is positioning the tool as enabling rapid prototyping and idea refinement, though it also introduces questions about content quality and platform saturation.

Roblox is implementing safeguards to prevent low-quality AI-generated content from dominating discovery, claiming that games will be ranked using the same retention-based criteria as manually-created experiences. Additionally, the company announced new AI agents for developers to assist with playtesting, analytics, and engagement optimization. Build will initially be free at a base level, with paid options available for power users, though pricing details are not yet public.

Editorial Opinion

This move represents a significant democratization of game development, but raises legitimate concerns about quality control on an already-saturated platform. Roblox's claim that AI-generated 'slop' won't surface due to retention-based ranking is reassuring in theory, but in practice could flood the platform with low-effort content that degrades user experience. The real test will be whether Roblox's discovery algorithms can truly distinguish between quality AI-assisted games and inevitable low-quality outputs.
