How I Build and Ship Ten Roblox Games With a Shared Engine and Local AI

I report on the construction and release of ten Roblox games, a web application, and a short-video pipeline, all spearheaded by a solitary individual operating from a single personal computer. The software stack includes Text generation through Ollama with Qwen3 14B, and the creation of images via Flux through ComfyUI. All these operations occur on the reporter's personal machine, hence no charges are incurred per usage, and there are no additional fees for publishing.

The ten games are live on Roblox, ranging from simulators to obbies, with a 16+ age rating. As of October 7th, 2026, they are all verified and published on Roblox. Player progress is safely saved, and a purchase is only confirmed after the save process is complete.

The web app, named Kairo, assists users by asking them about their skills, time, budget, and hardware. It then displays which AI-related methods of earning fit their situation. The basic package costs a one-time fee of €50. The system also generates short videos for Instagram and TikTok, with a single Telegram message being sent out per day.

Every content published goes through a rigorous approval process. The reporter's system operates under a strict rule of failing loudly on bad configurations. If the configuration file cannot be read, be it due to an invisible character or a Byte Order Mark, the entire process stops, and an alert is triggered.

The reporter adheres to the principle of 'facts first, style second'. Every text begins with a sheet of verified facts. If this sheet is outdated, no writing takes place. The quality check only evaluates the writing, assuming the facts have been settled beforehand. Two models are employed, with one responsible for drafting texts and the other for reviewing them.

The fact-checking process is kept separate from this review. Account IDs are stored as text to prevent any rounding errors that could lead to the wrong social account being targeted. Only one channel and one account are used for publishing content, ensuring that a piece of content is published through the correct account.

The reporter emphasizes fairness in the in-game economy, setting a cap on rewards and login streaks. Missions, for instance, offer a maximum number of gems per day. The aim is to ensure the game is fair for players who do not spend. The reporter ends by inviting readers to try one of the ten games on Roblox and observe the shared engine in action. It must be noted that this report was drafted using a local AI model, reviewed, and approved by the reporter.
