Nah, the prophecy was around even during the time of the experiments. In the Japanese script, when Solaris gets loose: "This is a Living Flame that has been handed down to our royal family. If nothing is done, the Flames of Disaster will awaken according to the legend!" We aren't told much about Solaris' personality, because it doesn't matter. 06's theme isn't about nature, it's about accepting loss. Solaris and his manifestations exist to give the characters opportunities to engage with that theme. When Elise blows out the flame, the focus isn't on Solaris' nature, but rather Elise's decision to do what her father couldn't and accept losing a loved one for the greater good. This is a contrast to SA1, where the game's resolution highlights Chaos and him finding peace. The manual describes the emeralds protecting Angel Island, which outside of Knuckles, only has animals. The Master Emerald was created by a sky god. The island falls to the ocean because of the Death Egg crashing into it, and the Master Emerald allows it to float again. The emerald allowing nature to heal after the Death Egg messed it up, sounds right in line with me. Anyhow, I feel you're missing what I'm saying. Conflict and theme are distinct things. For a video game, conflict is gonna be in the forefront but the theme helps give it a distinct identity. In S3K, Eggman is building Egg-shaped superweapons and fighting you with animal-powered robots, while in 06 he's fussing about over a princess and fighting you with nondescript robots. The latter is more generic, and that's what makes theme important. With Colors, the environmentalism theme is more in force, with Sonic and Eggman both using the Wisps for their own ends. It's obviously not a perfect encapsulation of the classic games (neither is SATAM, I mainly brought it up to point out that I don't think "darkness" is really the issue people have with 3D Sonic). But with Colors, with the environmentalism aspect returning and Sonic being the clear star of the show again, I'd say its closer to the originals than SA2-06.
