Imagine you are playing a game where you have to make a choice between two options. Let's say you have a choice between eating broccoli or ice cream. This is called a decision game.
Now, you might think that ice cream is the best choice because it tastes good, but if you eat too much ice cream, you might get a tummy ache. On the other hand, broccoli might not taste as good, but it's very healthy for you and will help you grow up strong and healthy.
So, in a decision game, you have to think about both choices and decide which one is the best for you. You might also think about what other people would do, or what you have done in the past. Once you make your choice, you have to stick with it and see what happens!
