So, does anyone actually live in Robotropolis? You never really see anyone walking around the streets except for Swat Bots, if there aren't any people walking the streets, what's the point? I mean I guess is supposed to show how desolate the place has gotten but what's the point of having all these streets if they're not even populated? Why hasn't Robotnik destroyed the streets and build more bases?
It's populated solely by robots, as Robotnik's plan seems to be to turn the entire planet into his robot slaves. It's less a city with streets than it is one big machine.
So it seems that Robotnik is Genre Savvy enough to know that the Freedom Fighters live in the woods, well why hasn't he decided to just bomb the entire forest? Robotnik has shown numerous times how little he cares for wildlife, why not bomb the forest and possibly kill your worst enemy, especially when you were essentially going to destroy them anyway?
Every time he tries that, the Freedom Fighters get wind of it and stop the plan.
In Blast To The Past, it's established for the most part that the time travel's of the closed loop type, as major details such as Robotnik's mechanized arm existed in episodes prior to Sonic's meddling with the past. This would mean that Sonic saw his own older self during his days shortly prior to Robotnik's coup. And this whole shebang happened at a point where for most characters this was one of the most important and memorable events in their lives: Young Sonic saw his uncle getting roboticized, Robotnik got afflicted with a roboticized arm, and both Bunnie and Antoine were about to be sent to their doom. Why does no one realize or reference this? Sonic in particular fails at remembering and predicting the actions of the older self that he's incarnating during the episode.
