Creativity[]
Creativity is a resource generated by your population, independent of their luxury needs being met. The principle is simple: the larger the population, the greater the creativity produced, although this follows a diminishing returns pattern.
Each population tier generates a distinct type of creativity, which can be allocated within their respective Research Trees. Moreover, creativity generated by higher-tier populations within the same region can be utilized to unlock perks in the Research Trees of lower tiers.
Creativity is produced by your population regardless of their luxury need satisfaction. The more inhabitants the more creativity gets produced with diminishing returns.
Infinite Creativity[]
The Infinite Tree taps into the creativity of populations whose Research Trees have been fully unlocked. This allows for the continued use of creativity resources even after the completion of a population's research.
