So, you see how life is scaled down to a 4x4 grid, and when people are playing it they don't realize it because their reality is on a much bigger scale. The rules are the same for everyone, i.e. you were born, you are going to get aged and one day you'll die. These three simple rules are for everyone, the world is different for everyone. Someone is religious, someone is atheist, someone loves to eat meat, someone is a vegan, and so on. Our decisions throughout our life shape how our life is going to be. Also, the simulator is designed by keeping an individual in mind, because my belief is that you are alone in the world. Your family, your wife, your kids are just other people you are an individual and you'll be answerable to your decisions only and no one can take your place no can you take someone else's place. That is why when you are playing the game you're all alone, all you have is a world that is changing with every decision you are making, either you'll succeed or just die.
