"Puse aumentar el bono por nuevos ciudadanos en nuestras ciudades. Por cada nuevo habitante que recluten se recibe este bono. Voy a seguir proponiendo leyes hasta que alguna se aprobada. Deben ser por lo menos 10 PERSONAS DISTINTAS para que la ley sea probada."
This bonus is a reward the country pays from its budget when a town gains a new citizen. The value is how much each reward pays out.
Raising the value pays a bigger reward each time, which makes the rewarded action more attractive but spends the country budget faster.
Lowering the value pays a smaller reward each time, which saves the country budget but gives citizens less incentive.
This is a neutral explanation to help you decide — it doesn't favor either side.
