In this 4th book in his edutainment book series, Mr. Ventrello profiles the first game systems to use CD-ROM. More data was available to create higher quality games than was possible on a cartridge. At this point some of the greatest edutainment games would be made, even if the game systems themselves weren't that successful. Mr. Ventrello discusses edutainment games on the world-changing Sony Playstation, the 3DO, the Sega CD, and the ill-fated Philips CD-i. He is a firm believer in the value of edutainment gaming, and after reading this, you will be, too!
