    Overview

    µCity (also spelled uCity and pronounced micro-city) is Antonio Niño Díaz's open-source city-building game for the Game Boy Color. The aim is simple enough: build a city. You can begin with one of the predefined scenarios or with a completely empty random map, and the number used as the seed always generates the same map, so a good one can be played again.

    Most buildings can be placed by the player, but the most important ones cannot. Houses, shops and factories must be created by the city itself inside the residential, commercial and industrial zones you lay out; the player can only try to attract people. Their happiness depends on services, transport, power and pollution, and the services they expect grow as a village turns into a town, a city, a metropolis and finally a capital.

    Fires can break out at any time, and fission power plants can melt down. The only way to lose is to post a negative budget four times in a row, after which the population removes you from your position as mayor. There is no way to win: in the author's words, the satisfaction of a fully developed city should be enough for everybody.

    The game uses most of the extra memory added to the Game Boy Color, which is why there is no version for the original monochrome Game Boy.

    Tips

    1. Roads and train tracks count as connected when they simply sit next to each other, even if the tiles are not drawn as joined, so you can switch from road to rail without a special junction.
    2. Power lines are the only thing other buildings can be placed on top of, so lay them freely across empty land and build over them later instead of paying to demolish.
    3. Universities are the only way to raise the technology level. Each one tries once a year, and fission plants unlock at level 10 and fusion plants at level 40, so build universities early if you want nuclear power.
    4. Solar plants produce more in summer and wind plants more in winter; pairing the two keeps output steadier across the year.
    5. To stop a fire, demolish every tile around it as fast as you can. Building still works during a disaster, and more fire departments lower the chance of fires starting at all.
    6. Only four negative budgets in a row end the game, and each positive budget counts the streak back down, so a loan from the bank to get through a bad year is safe as long as income recovers. Negative funds alone do not count.
