GameRevolution: "It was unfathomable when Hideo Kojima had a dramatic break-up with Konami. Working together for 28 years didn't seem to matter as both the legendary Metal Gear creator and Japanese publisher split paths in a way that left gamers in shock.
No official reason has been given for the break up, but the recent release of Metal Gear Solid V: The Phantom Pain offers a clue as to what happened.
The initial wave of acclaim following MGSV: The Phantom Pain's release has been largely replaced with discussion about how its story didn't live up to expectations—as a Metal Gear fan I certainly agree. Although its superb presentation and gameplay challenge any notion that it isn't a great game, fans expecting a mind-blowing conclusion to the Metal Gear saga anywhere near as interesting as the pre-release hype (i.e. Moby Dick Studios) have been left scratching their heads."
