@TailsX No he's saying that in an interview the developers said that they thought it'd be a waste if they didn't use the layout they made for Cyber City, and repurposed it into Metropolis Act 03
Oh hey, a Cyber City recreation that actually uses the tileset originally made for it that was then later recycled for B-Bomb before it was cancelled, nice. Now if we can get a recreation that uses those tiles and uses Metropolis Act 3's layout, we'd have a winner!
I always see this same thing that Sonic Spinball’s “The Machine” recycled assets from Cyber City but I can never find a direct official source for where this idea came from. Did a developer confirm it or something?
That genocide city I think but who knows they changed things around so much and didn’t leave time to make the game as good as it should have been although it did still turn out pretty well for the most part but a lot of the missing stuff and the title screen graphics were way better
The "one with the storm" is Genocide City Zone from Sonic 2: Long Version, which is a different ROM hack. The background pallette in that level, i.e. the city at nighttime, was mostly derived from a 1995 SNES game called Spirou, based on the Belgian comic of the same name. The original version of the level, as planned by SEGA, was called Cyber City Zone and had the pallette seen in the video, if I recall correctly. The Japanese designers originally callled it Genocide City Zone because they wanted the level to have a serious sounding name, but they didn't know the actual meaning of "genocide"; once they did figure it out, Cyber City became the level's new name.
They're the same level, the name was changed during development And that's not Cyber/Genocide City's theme, no one quite knows what it would be, the only official build that we have access that kinda included it as a stage reused Chemical Plant's theme, while Carnival Night's 2P theme was used for Oil Ocean
