• Initialize()
– Allows the game to perform any initialization it needs to before starting to run.
– This is where it can query for any required services and load any non-graphic related content.
Calling base.Initialize will enumerate through any component and initialize them as well.

Update() vs. Draw()
Update() vs. Draw()
• Update and Draw are called at different rates depending on whether
IsFixedTimeStep is true or false.
– If IsFixedTimeStep is false, Update and Draw will be called in a continuous loop.
– If IsFixedTimeStep is true, Update will be called at the interval specified in TargetElapsedTime,
while Draw will only be called if an Update is not due.
– If Draw is not called, IsRunningSlowly will be set to true.
