broker tycoon

A single-file tycoon where the resource you optimize is other people's personal data — you grow a brokerage using mechanics the author says are drawn from real industry practices, and the growth loop doubles as a walkthrough of how that data actually gets collected and sold. The subject is what makes it worth a look: most idle games have you stacking abstract coins, this one aims the same dopamine loop at something uncomfortable and real. Zero stars, no install, runs in the tab.
