Roblox will let people use AI to make games on their phone
Roblox is introducing "Build", a mobile-first tool that lets users generate basic games from text prompts directly within its app, marking the company's latest push to embed AI throughout its platform. The feature could make it far easier for anyone to create games, but critics worry it may worsen concerns about low-quality, AI-generated "slop" flooding a platform already criticised for uneven content standards; Roblox insists its discovery systems favour games with genuine player retention, so unplayed AI-made titles will not be promoted.
Build handles gameplay mechanics, environments, characters, visual style and sound, drawing on both Roblox's own AI models and open-source ones. It launches in public alpha on 28 July, initially limited to age-verified users in New Zealand aged nine and over, though published games will be playable globally by users 16 and up. A basic version will be free, with paid options for power users planned but not yet detailed. Roblox also plans further AI agents for developers, including tools for playtesting, analytics and engagement experiments, expected in the coming months.
In short
- Roblox's new "Build" tool turns text prompts into mobile games
- Alpha launches 28 July in New Zealand, ages 9+ with verification
- Free basic tier planned; paid options and more AI agents to follow
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Making game creation accessible via text prompts could enable millions without coding or artistic skills to participate in development, expanding creative opportunities significantly. If Roblox's discovery algorithms prioritise player retention over volume, low-quality content will be filtered out through lack of engagement, preventing platform degradation. This could create opportunities for a wider pool of creators and accelerate innovation through experimentation at scale.
The case against
Whilst AI tools lower creation barriers, they tend to produce derivative, unpolished content lacking the human creativity and craft that makes games engaging. Even sophisticated discovery algorithms can be overwhelmed when volume increases dramatically; countless mediocre AI-generated games could clutter the platform and hinder discovery. This threatens both user experience and the livelihoods of human creators who invest significant time and skill, potentially commodifying game creation into volume-based competition rather than quality-based recognition.
Explained simply
Roblox is a vast online platform where millions of users, predominantly children and teenagers, create and play games made by other users. The platform has become hugely popular over the past decade, with people earning real money by creating popular experiences and Roblox taking a cut of revenue.
The company is now introducing "Build", a new mobile tool that uses artificial intelligence to generate games from simple text descriptions. Instead of learning complex programming or design skills, users will be able to type ideas into the Roblox app on their phone, and the AI will create functional games with gameplay, characters, environments and sound.
The move reflects a broader industry trend of using AI to democratise creative tools, making game development accessible to casual users. However, it raises concerns that the platform could become flooded with low-quality AI-generated content that detracts from human-made games. Roblox argues that its systems prioritise games that attract and retain real players, meaning unplayed AI games won't gain visibility.
