Originally the Playstation was going to be a add-on for the SNES that used CDs a game format. Similar to Sega’s Sega CD add-on for the Genesis. There was a dispute over money, so Nintendo opted to go to Phillips instead. That deal eventually broke off, but led to the Phillips CD-i and them having the rights to make really bad games with Nintendo characters. This move got Sony feeling betrayed which led to the creation of the Playstation which crushed the N64 in sales, as did the PS2 to the Gamecube.
