The sentence you type
"Make a factory sim. Start with one resource, one machine and one conveyor."
The brief the AI writes back
First playable: one resource, one machine and one conveyor. The loop to get right: mine, transport, craft, automate.
Build, play, adjust
Compare with the games that define the genre: Factorio (Wube Software, 2020), Satisfactory (Coffee Stain Studios, 2024) and Shapez (tobspr, 2020).
What makes it finished
