How Developers Are Using AI in Game Development
PocketGamer.biz surveys how game developers currently leverage AI across production, data analysis, and user acquisition, ahead of the AI Gamechangers Summit at Pocket Gamer Connects Nordics. Executives from MTG, NC/Veroplay, Fingersoft, Dodreams, Julicia Studio, and Mattel163 share concrete use cases: AI enables three games to be built instead of one (MTG), cuts creative costs by 20-30% (Veroplay), and improves data analysis and actionable insights (Dodreams). Mattel163 uses AI for pLTV modeling and ROAS prediction to optimize UA spend. Studios report cost reductions, faster workflows, and enhanced testing, while noting incremental gains in art and Unity development. Hypergryph's Arknights: Endfield uses almost no AI, starting before the hype. The article positions AI as a practical tool improving efficiency and creativity, not a replacement for talent.
Roblox launches AI game-creation mobile feature
Roblox unveiled Build, a mobile-first, AI-powered game-creation feature that generates playable game starting points from simple text prompts inside the Roblox app. Build uses a mix of open-source and proprietary Roblox AI models to produce gameplay mechanics, environments, characters, visuals and sound, and it shares back-end models, chat history, and projects with Roblox Studio so creators can move work between mobile and desktop. Public alpha begins July 28, 2026 in New Zealand for users aged nine and older; publishing and select features will require age verification with publishing limited to older users (16+). Roblox will surface AI-generated experiences based on player retention and maintain existing safety reviews. The company is also testing agentic AI tools for playtesting/analytics and developing foundation models for 3D asset and scene generation, a launch that has sparked debate over low-quality, repetitive AI games.
Roblox expands AI game creation and cross-platform play
At its annual Roblox Developer Conference, Roblox announced new features including expanded AI-powered game creation tools, the ability to publish games as standalone apps on mobile, PC, and consoles, and in-browser play via links. The 'Build' feature, which allows natural language game creation, is expanding from New Zealand to Serbia and Singapore, with desktop access and a scene-generation feature planned. Roblox also introduced new NPC capabilities, an offline mode, a Friends chat tab, and a discovery algorithm that matches game length to user age. Financial products were unveiled, including a Roblox Wallet for daily real-money payouts (partnering with Airwallex for US users) and a Roblox Card for spending earnings. Since 2013, creators have earned over $5 billion, with $1.7 billion in the last 12 months. CEO David Baszucki reported over 29 billion player hours in the last quarter.
