And how did Superman: Ultimate Flight at Six Flags Over Georgia so affect the amusement industry and park rides such that they were forever changed? It is merely a B and M rendition of a Vekoma prototypical ride, Stealth later known as Borg: The Assimilator now known as Nighthawk at what was then Paramount's Great America and then Paramount's Carowinds, now simply Carowinds. Nothing ground breaking or world changing about it.

Plus this thread is about what ride at Kings Island will eventually become an ACE Landmark, if any more do. Certainly one cannot seriously contend that Firehawk will...

Batman at Six Flags Great America is an ACE landmark. It's the first inverted coaster. It's less than twenty years old and contains OTSRs.

I think that Vortex should become an ACE landmark, being the first mega looping coaster.

Batman at Six Flags Great America changed the future of roller coasters dramatically. Can the same be said for Vortex? Not really.
