[ORIGINAL UNIVERSE] [vaguely similar shit happens that vaguely echoes the games series as we know them, probably the GG versions of the original series] --> 06 -->
[SOFT RESET OF THE UNIVERSE 1]* --> SegaSonic --> 1 --> CD bad future --> 2 --> 3nK --> Adventure 1 --> Adventure 2 --> Heroes --> Shadow --> [Elise feels the wind in 06's ending] --> Rush --> Unleashed --> Rush Adventure --> Colours --> Generations -->
[SOFT RESET OF THE UNIVERSE 2]** --> SegaSonic --> 1 --> CD bad future --> 2 --> 3nK --> Generations --> 4e1/Tails Adventure --> 4e2 --> [hypothetical 4e3 OR the Fighters, but not both] --> Adventure 1 --> Rush --> Unleashed --> Rush Adventure --> Colours --> Generations --> [Continued feedback into the 2nd soft reset] --> Lost World --> [???]
*Eggman's interactions with Sonic and co in the original universe- existing as inklings of memories- give him a serious upper hand. It alerts him to the existance of the Echidna tribe (bringing Angel Island and Chaos to his awareness), greater knowledge of time travel (which allows him to track down and chain the Little Planet for easier control of the flow of time), knowledge that GUN have Shadow in their posession and being able to intervene earlier to stop the black hedgehog being used against him, and knowledge that Sonic is his nemesis in advance, leading him to track down and attempt to destroy his future nemesis before he'll be a pain in the butt in the first place. Also, the freeing of the seventh Chaos Emerald from its unstable time loop (thanks BlackHole!), allowing the stakes to be raised significantly.
**Classic Sonic is re-inserted into the timeline at the end of S3nK, his earlier-than-usual Homing Attack development seriously derailing the timeline. Specifically, he's rocked enough by this newfound knowledge of his future self that he goes off on his own, splitting from Tails for a bit- and discovering Eggman's trying to take control of the Little Planet once again. In the original soft reset universe, Eggman conquered the Little Planet without Sonic knowing, scorching its surface so it would be the barren moon seen in the beginning of Sonic Adventure 2... having been his grandfather's ARK this entire time. Sonic's defeat of Eggman and reclaiming the Little Planet a second time would mean Shadow is never revealed from his slumber in this timeline, would remove the events of Adventure 2 to Shadow entirely, and would mean Shadow only shows up in Generations onwards thanks to the soft reset universe timeline. This would explain his absence from the original party at the beginning of Generations. His presence in 06 from the original universe could be explained as GUN using Shadow (who they had in storage at the beginning of SA2) as a weapon against Eggman.
I dunno. It kind of makes sense, I guess. I kind of want consequences for Sonic choosing to erase his timeline at the end of 06, because you shouldn't be able to just do shit like that and get away scott free.
