TL;DR: In the late 1980s and early 1990s, Nintendo partnered with Sony to develop a CD-ROM add-on for the Super Nintendo Entertainment System (SNES). The partnership collapsed dramatically in 1991 when Nintendo publicly announced a new partnership with Philips instead—one day after Sony had announced its collaboration with Nintendo at the Consumer Electronics Show (CES).

In the late 1980s and early 1990s, Nintendo partnered with Sony to develop a CD-ROM add-on for the Super Nintendo Entertainment System (SNES). The partnership collapsed dramatically in 1991 when Nintendo publicly announced a new partnership with Philips instead—one day after Sony had announced its collaboration with Nintendo at the Consumer Electronics Show (CES).
The fallout from this dispute directly led to Sony creating the original PlayStation and permanently reshaped the video game industry.
The Contract Problem: The agreement gave Sony major control — Sony controlled "Super Disc" format, CD game licensing, royalties. Nintendo feared losing its monopoly on game licensing. Hiroshi Yamauchi realized the contract could give Sony leverage over Nintendo's software ecosystem.
Nintendo's contractual obligations led to Philips creating games using Nintendo characters on CD-i:
Nintendo had little or no direct involvement. These titles are among the worst associated with Nintendo properties.
CD-i was a multimedia system (encyclopedias, training), not a game console. Weak sprite support, IR remote controllers, ~$700 launch price vs. SNES ~$199.
Ken Kutaragi convinced Sony to build their own console. CD-ROM, strong developer support, easier tools, aggressive third-party courting. PlayStation launched 1994 (Japan), 1995 (worldwide).
Why Square Left Nintendo: N64 cartridges 8–64 MB vs. CD ~650 MB. Square's cinematic vision for FF7 required far more storage for CGI cutscenes, voice clips, large world assets.
Move to PlayStation: Square moved FF7 to Sony's platform — a massive strategic win for Sony.
Marketing: Sony treated FF7 as system seller. Development ~$40–45M; marketing ~$20–100M. Total investment possible $80M–$145M. Sold ~10 million copies; helped cement PlayStation dominance.
Super Mario RPG: Legend of the Seven Stars (March 1996 Japan, May 1996 North America) was a joint Square–Nintendo project announced in 1995 — the same period when Square was actively developing Final Fantasy VII for PlayStation and preparing to defect. The timing is more than a little suspicious.
The Project: Directed by Chihiro Fujioka (Square), produced by Shigeru Miyamoto (Nintendo). Yoko Shimomura composed. The game fused Square's RPG expertise (turn-based combat, party dynamics, narrative depth) with Nintendo's Mario legacy (platforming, jumping, tactile controls). It was explicitly framed as "the best of both worlds": an RPG where no blood is shed, with characters that children and adults could love. Heavy tradition — Miyamoto insisted on the hammer; Square had to drop their weapon-centric RPG dogma to fit Mario. The result was an evolved narrative experience, warm, self-reflective, and broadly inspirational.
The Signal: For fans, Super Mario RPG seemed to announce that everything was alright in the Square–Nintendo relationship. Here was a dream collaboration: two revered developers, mutual respect, a shared ambition to "bring out the best of Mario" and reach worldwide audiences. The game was a love letter to the partnership — Square and Nintendo at the table together, Miyamoto and Fujioka in good-natured dialogue, "we freed ourselves" of established-series restrictions to make something new. Best of all worlds.
The Irony: Months after release, Square announced FF7 would be PlayStation-exclusive. The divorce was already in motion. Square had been courting Sony while Nintendo believed the Mario RPG collaboration signified commitment. In hindsight, Super Mario RPG reads as either: (a) a sincere final gesture before the split, (b) a calculated reassurance to keep Nintendo passive while Square completed the defection, or (c) a cruel coincidence. Whatever the intent, the game has aged into a poignant artifact — a last shared moment before the rift, suspended in the moment when it still seemed possible that Square and Nintendo could build something lasting together.
Nintendo leadership viewed Square's departure as a betrayal. Square released no major games on Nintendo platforms for years. Relations improved after Yamauchi stepped down, Square merged with Enix, FF Crystal Chronicles (GameCube 2003).
