Idle City Tycoon: Money Empire

This is a portrait-oriented idle tycoon game where players manage and upgrade city buildings. While sessions are short and the game can be played offline and one-handed, progression is heavily gated by energy timers and a pay-to-win monetization model that forces purchases to advance. It's best suited for players who enjoy long-term idle progression and don't mind a slow pace or spending money to speed things up.
