AGING/TIME PASSING
Characters and the world change as calendar time advances — people age, skills decay or mature, generations succeed each other, and long-term consequences accumulate beyond any single session's actions.

Crusader Kings III makes aging the engine of the whole game: your ruler will die, so play is about heirs, education, and dynasty rather than one immortal avatar. The Sims 4 runs life stages from infant to elder, with each stage gating different interactions and goals. Designers use aging to create stakes no health bar can (mortality, legacy), to force roster turnover that keeps strategy fresh, and to make the world feel like it exists independent of the player. Key decisions: the ratio of real time to game time, what actually changes with age (stats, appearance, available actions), and whether death of a favorite character transfers control or ends the run. Pitfall: aging that is pure decay reads as punishment — the systems that work give each life stage its own strengths and turn generational handoff into a strategic layer (inheritance, mentoring, heirlooms) rather than a reset.
