Once upon a time there were plans from Nintendo and Sony to release a CD-ROM peripheral for the Super Nintendo. It was called PlayStation, but something happened - Sony decided to go on by themselves and the rest is history.
But now Nintendo Everything has found out some more details regarding this joint effort and why it was cancelled from a former Sony exec, Shigeo Maruyama.
He says Ken Kutaragi was pushy during the development, and that the Nintendo of America boss at the time, Minoru Arakawa, warned Nintendo that Kutaragi might end up taking over the whole company. Also, the CD-ROM itself wasn't meant for video games, but rather "everything but video games", and one of the planned softwares for this unit was karaoke.
Obviously Nintendo listened to Arakawa and let Sony go on by themselves. This made Kutaragi angry and he used the situation to create PlayStation to try to beat Nintendo, saying Sony's honour was hurt. Sony did have a contract with Nintendo and why they didn't try to file a lawsuit is unknown, and might stay that way until Kutaragi himself decides to share his version of the story.
Question is, which side ended up better off? We'll let you decide that one.
