New details on Bungie's canceled game 'Gypsum'

On IGN Unfiltered former Bungie employee Marty O’Donnel reveals some interesting information on a canceled game they were planning called ‘Gypsum’. After Halo: Combat Evolved launched this mythical fantasy action game was in development. The game was being built using the Halo engine and helmed by two people who made their mark through a Myst mod known as Chimera. There was a version of the game that was playable believe it or not. Marty said it included gameplay revolved around a playable Minotaur, and let players use a hammer and magic to interact with the world.
Since Halo became a huge hit this game was canceled and the team working on this game were brought onto the Halo 2 team.
Marty on Gypsum:

It was…it went very, very far. There was a playable prototype that was a blast. I did music for it, sound effects, everything.

If Halo was never a hit I wonder if this game would have made it far or even if Bungie would have made it far. We can’t go back in the past but Bungie has a very interesting history which I love hearing about.
