The Philips CD-i was never a big hit. It was expencive and had more or less crappy games. The video bellow, linked from Gametrailers.com, show you the CD-i. But you should also take a read at N-sider.com and consoledatabase.com which cover the SNES CD-ROM add-on, and the history also invovles the original Playstation. Videogame history is fascinating!
