We now roughly know what type of game we're going to make. Don't worry too much about the exact details as it will not affect the development phase. Our main focus will be the framework of the game; we'll focus on cosmetics in a later chapter.
It's very easy to jump into game development and make it up as you go along—sometimes, that's half of the fun. But when it comes to the fundamentals of creating any application, we need to know where to throw our creativity and logic by sticking to a particular development process. Ideally, you need a framework.
Before I carry on presuming you know what a framework is, let's just consider it as an overall blueprint—a plan of how all our code is going to talk to each other. Frameworks are similar to design patterns—the plan of the code is set out and ideally shouldn't be expanded on because we're sticking to a plan.
