This title developed by Silicon Knights, was first presented in a playable form at E3 1999, on the original Playstation. It collected immediately the attention from the critics and the public, not only for it’s good graphic (at least for its time), but even for an interesting and promising gameplay.
The release of the game was scheduled for summer 2000, on more than 4 CDs, filled with an huge world, an immersive story and hours of FMV movies… but it was never finished. At that time Nintendo, after seeing the excellent work that Silicon Knights were doing on Eternal Darkness (at the time in development for N64), decided to take over the team, making it one of its numerous 2nd parties.
After the cancellation of the PSX version of Too Human, there were rumors that the development of the game was switched to the GameCube. Those rumors were confirmed at SpaceWorld 2000, with a FMV presentation of Too Human for the Nintendo console. But even the GameCube version was never finished.
In 2005, Silicon Knights went under the control of Microsoft and the Too Human project was moved to the XBOX 360. The game was finally released in 2008, even if it has lost many of the original features.
