Houses should grow up only when their needs stay met for days, not for a moment

A market truck passes once and a house jumps a level, then drops again the next day when the truck is gone. Neighbourhoods look like a blinking light. This entry shows how to make growth feel earned and decline feel fair, with a counter on each side and a rule for what happens to the other one.

Why this works

One good day proves little, but a run of them shows a lasting situation. Counting days in a row, and wiping the count whenever the streak breaks, makes a house change only when its condition has truly settled, and the fresh start after a change fits the new needs.

When not to use it

Skip it when the player expects an instant reward for fulfilling a need, as in a quick, playful town builder where waiting would feel dull. Upgrade right away there, and keep the waiting rule for games that value slow, steady growth.
