Timelines: Age Assignment Mod is a gameplay mod that gives your Sims actual, realistic ages rather than relying on the game’s broad life stages. Your Sims will no longer go by “Young Adult” or “Adult.” Instead, they’ll have a specific age in years, like 20 or 21, which adds a whole new level of depth to storytelling, legacy gameplay, and rotational saves. If you care about realism or structured storytelling, you need to download this mod. It lets you define exactly where your Sim is in life. It also introduces more detailed age categories, which are: These ages appear in the Simology panel, so you can easily track your Sim’s life timelines at a glance. Whether you’re playing a legacy family, historical save, or just want more control over your Sim’s life progression, this mod makes your gameplay feel far more detailed without overcomplicating things.
