At the core of this magnetic allure is the pursuit of the 'rich9' experience—a term now synonymous with those seeking richness in gaming depth, mechanics, and enjoyment.

The genre thrives on its versatility, offering players a wide range of scenarios that cater to different tastes. From constructing entire cities in games like SimCity and managing sprawling farms in Stardew Valley to piloting complex aircraft in Microsoft Flight Simulator, simulation games provide a playground for gamers to indulge in roles and worlds that push the boundaries of reality.
