If you have a bunch of components you want to be singletons, I'd make a SingletonGameComponent class which derives from GameComponent and adds in the singleton behavior. You could do the same with DrawableGameComponent to make a SingletonDrawableGameComponent if you wanted.

Let's say I wanted a Singleton GameComponent. I obviously can't inherit from both, and I'm having a hard time thinking up a design without re-creating the Singleton class for each type where I would need to inherit from multiple classes (I have a GameBase class that inherits from Game that I think would be helpful to make a Singleton, as well). Any ideas? Nick,

My implementation is a little more involved than yours ( I like the simplicity ) but does provide a threadsafe instatiation. http://blog.magenic.com/blogs/michaelc/archive/2006/03/11/Simple-but-it-works.aspx Nick,
