Unlock the Secrets
GameWizards released interactive strategy guides for several popular games between roughly 1996 and 2000. These products were budget priced and published by WizardWorks. They also released traditional book strategy guides. Both of these are often now difficult to find.
These items were ahead of their time, essentially "Let's Play" walkthroughs distributed on discs. They often included maps, tips, written walkthroughs and other extra content.
