Simulation games are a genre that mimics real-world activities, systems, or scenarios, offering players immersive experiences in virtual environments for entertainment, education, or training, often with non-linear progression and few strict goals, focusing on management, building, or life aspects, like flying planes, running businesses, or managing virtual lives. Key elements include realistic mechanics, strategic planning, resource management, and creative experimentation, spanning subgenres from flight/driving sims to city-builders and life sims.
