Urien's ending in Street Fighter III: 3rd Strike was going to be somewhat different, as seen in early storyboards.

The storyboards show that the building of the secret society was going to be a modern skyscraper in the middle of a city while the final game shows a building similar to the Tower of Babel in the desert.

Additionally, the ending featured a giant sphere containing the brains of past Illuminati leaders. This was replaced in the final game with tubes containing the bodies.
