Ratopia Rule rats, tax wisely

Most colony sims hand out resources from a shared pile. Ratopia gives every ratizen their own wallet. They work for wages, buy what they need, and the state lives off what you decide to take in. So the tools are unusual for the genre: set tax rates, set wages, write laws, hand out welfare or squeeze everyone for profit. Tax too hard and the city turns on you; tax too little and the treasury runs dry. Finding the balance that keeps both the rats and the budget happy is the heart of the game.

Your ratizens are not anonymous workers. Each one carries their own wealth and their own personality, and they react to how you govern. Supply jobs and services to keep them content, watch a whole profession slide into poverty and start begging for bread or turning to crime, or push them to work tirelessly for the good of the treasury. Policies can create social disasters or prevent them, and it is entirely your call which. One player even instituted a toilet tax in the spirit of ancient Rome. If you can imagine a state model, Ratopia mostly lets you try it.

You start as a monarch with next to nothing and lay out a city block by block: dig into dirt, stone, iron, copper, grass and mud, all of which get consumed as materials, then raise housing, workshops and services as the population grows. Layout matters, because badly placed infrastructure wastes everyone's time, and a shortage in one resource can stall several industries at once. Progression climbs steadily, from leaf ladders to wood ones to rope and electric elevators. And since every goal favors different buildings and citizens, each new city comes out differently.

Under the pastel art sits a demanding survival sim. Overextend the population and the food runs out; skimp on hygiene and disease spreads faster than you can treat it; let complaints pile up and a revolt breaks out. Raiders and invaders arrive on a schedule, and the defenses that handled the early waves will eventually need proper soldiers and fortifications. It is genuinely difficult, and a first run can end in bankruptcy or starvation. But once income, food, sanitation and entertainment all hum along at once, the game turns into the kind of busy, absorbing management you lose whole evenings to.
