Roblox lets anyone build games by typing text, and developers are worried

Roblox is handing the keys to game creation over to anyone with a phone and an idea. The company announced Build, a new AI feature that turns text prompts into playable games, with public alpha testing set for July 28 in New Zealand. Type something like “a cozy adventure game in a dense forest” and the system generates the environment, characters, mechanics, and sound — no coding required.

This isn’t a one-model stunt. Roblox says Build pulls from a mix of open-source and proprietary AI models. Users can tweak what the system spits out, then share it with friends. Those 16 and older can publish globally. A free tier exists alongside paid options, though pricing details are still vague.

But the announcement lands at a tense moment. More than half of game industry professionals — 52%, per this year’s GDC State of the Game Industry survey — believe generative AI is actively hurting the field. Their fear isn’t abstract. When anyone can churn out a game in seconds, the platform risks drowning in what critics call “AI slop” — repetitive, low-effort experiences that make it harder for skilled creators to get noticed.

Roblox’s defense is algorithmic. The company says its discovery systems already prioritize long-term player retention over novelty. “If no one plays it — no one can find it,” the blog post states, bluntly adding that the homepage won’t become a showcase for AI-generated junk. Build is part of a broader AI push that includes a 3D asset generation model, a developer support chatbot, and a scene-generation model that can create fully editable 3D environments from a single prompt. The company also confirmed it’s killing Roblox Connect, its avatar-based video calling feature from 2023. For Roblox, the bet is clear: AI isn’t just a tool for creators — it’s becoming the creator.
