Grow a City

Grow a City is a city-building tycoon on Roblox developed by 0 Thought Games - the same group behind Grow an Army - where players purchase buildings, place them on a private plot, and generate passive Cash income that accumulates even while offline. Released in June 2025 and last updated February 2026, it has reached 4.7 million visits and 12.5K favorites with a 94.8% approval rating from 28K+ votes. Servers cap at 5 players, creating an intimate personal progression experience.

The entire loop runs through the Building Shop, and the goal is straightforward: accumulate enough Cash to keep purchasing and placing buildings until you reach MEGACITY scale:

• 🏠 Buy buildings from the Building Shop and place them on your plot to generate passive Cash income
• 💰 Buildings continue earning Cash offline, so every login rewards you with accumulated earnings
• 🏠 Reinvest into more expensive and higher-output buildings to grow your city faster
• 🏆 Scale your settlement from a small plot into a sprawling MEGACITY

Cash is the sole resource. Buildings are the items. There is no combat or PvP - the focus is pure building progression. Plot expansion gamepasses (Medium Plot 15 Robux, Big Plot 25 Robux, Bigger Plot 45 Robux) let players unlock more land to place additional buildings, accelerating income growth without high cost.

Grow a City runs on the same template as Grow an Army from the same developer - identical offline Cash mechanic, identical 5-player server cap, and the same plot-expansion gamepass structure. Both games were released within weeks of each other in mid-2025, applying the formula to different themes.
