Ben, in the book, says "Microsoft also added the LoadGraphicsContent and UnloadGraphicsContent helper methods by default to the Game1.cs class...but these methods will never be used in this book because it is much simpler to have all initialization and loading code at one place in the Initialize function". But in the first examples Ben uses the LoadGraphicsContent to load the code. Is there a difference?

Initialize method will only be called ONCE. (ie. when the game is started)
The LoadGraphicsContent MIGHT be called several times. (ie. when the game looses its graphics context for some reason like when the game is minimized or a screensaver starts or something like that)

Graphics Content is directly tied to the graphics context, so when the context is lost, the content needs to be reloaded. Placing the content loading in LoadGraphicsContent makes sure that xna can reload the appropriate content when the graphics context is first created and when it is lost and regained.

Correct me if im wrong.
