Metal Gear Solid 5 famously released in two highly disproportionate parts, with its short (but highly replayable) prologue Ground Zeroes releasing roughly a year before the full-fat Phantom Pain.
This has always struck me as an odd decision. Prior to Ground Zeroes' release, Hideo Kojima claimed he split off the prologue because he wanted to give fans something to play. Yet I've always believed pressure from Konami played a big role, especially given how The Phantom Pain itself was noticeably unfinished (though still brilliant) when it launched, and Kojima's departure from Konami shortly after the game's release.
