Simulation games are kind of like playing pretend, but on a computer or phone. When you play a simulation game, you get to control everything that happens in a pretend world.
For example, in a farm simulation game, you get to be a farmer and plant crops, take care of animals, and sell things. You have to make choices about what to do and when to do it.
Some of these games are very realistic, which means they try to make everything look and feel like real life. You might have to pay attention to things like the weather or how much food your animals have.
Other simulation games are more fantasy-based, which means they give you more make-believe options. For example, you could pretend to be a wizard or a spaceship captain.
Playing simulation games can be a lot of fun because you get to use your imagination and make your own choices. It's like having your own pretend world that you get to control!
