Disabling DRM on Optical Discs?

There are many software packages available which will rip the contents of an optical disc and in the meantime it will remove any Digital Rights Management which may be in place.

Many people use either DVDFab or AnyDVD to rip movies and disable DRM.

People use software such as CD Clone in order to rip audio from a CD and disable any DRM.

So what software is used to disable DRM on a video game? Could you do that with DVDFab?

Also is DRM only in place for Music, Movies and Video Games?
