game object?

Instead of sending the game through the constructor, could we not have created a game object directly in the prompter class?

You could, but it wouldn't make much organizational sense, the prompter's job is to prompt, not actually handle the game logic. In computer science we call this The Separation of Concerns Principle, and it is an extremely important principle. Basically your program should be split into distinctive parts and each part should simply be in charge of it's own thing, or concern. There are many reasons for this but the most important one is for maintenance as objects that do things outside of it's scope can become harder to debug and add/remove to.

In short The prompter is it's own thing, it is in charge of prompting the user, not for creating the game itself.
