Thinking about the whole project silver thing again
-Belle still being around, having had a lot of rotten wood replaced with Tails' help but keeping whatever she still can of her original design-probably keeping a garden with a bunch of old Badniks and probably also a sanctuary in case something in the future goes wrong-taking care of herself and others for her old friends' sake despite hurdles
-Gemerl either powering himself down after Cream passed away(she probably lived the longest out of the OG Sonic crew) or also keeping a Chao Garden in her memory
-The crew making a time capsule for Silver to dig up in 200 years to avoid paradoxes-including albums full of the photos and memories they took together, some of Tails' inventions, some gifts from Amy and the others, some hand-carved stone gifts from Knuckles, some music, a kunai from Espio, some drawings from Charmy, and possibly preserved food and stuff in case something went wrong in the future(someone slipped in a ouija board to 'keep in touch! :D', and Silver has no idea who it was)
-Sticks is somehow still alive because she was prepared for literally everything
-Overall the group definitely has a museum, Tails had at least one university/school named after him, and accessibility in tech has SKYROCKETED-so the future isn't entirely all that bad. No matter what their fates were in the end, the love they shared with the world lived on in some way. Amy's grave is probably a massive rose garden.
-Rouge probably has some descendants after settling down, Omega and Shadow look after them for her sake
-Someone definitely reincarnated
-Speaking of reincarnations, there is definitely a Chao somewhere that has consistently reincarnated to take after Cream's image-perhaps a descendant of Cheese?
-The Chaotix definitely have a descendant who's an amateur detective that's fueled by caffeine
Idk I'm just throwing stuff around
