 To do this, the team looked at all of the visuals from the original game to determine where they could give the settings depth and interaction, including original design concepts that were omitted due to the limitations of the technology in 1997.Gilray always wanted to see a version of the game running with realtime 3D art to give the world life, and now the new version has clouds moving in realtime, critters running around, living factories, and flocks of flying birds that create a realistic environment around the player.
