Struggling to get my first users for a Nanocorp Polsia style tool any marketing advice? i will not promote

This project is a tool inspired by Nanocorp and Polisia, designed to help users simulate or manage corporate-style structures and operations, likely for gaming, worldbuilding, or organizational experimentation. It targets creators, developers, and hobbyists who want to build intricate fictional or real-world corporate systems. The project is interesting because it tackles the universal startup challenge of user acquisition for a niche, complex tool, seeking marketing advice without self-promotion.
