Simulation games do an excellent job of transporting players to a different environment, and they are the most immersive.
Simulation games have grown in popularity in recent years because they allow players to live a life that isn’t their own. Some of these games are extremely realistic, while others allow players to immerse themselves in a fantasy world. Because of the freedom these games provide, some players may wonder which of these simulation games is the longest.
