First, it's still true that $30 million today buys less steel than it did in 2014, and there's no indication that's changing anytime soon. So should they wait twenty years? Fifty?
Second, these parks have access to data that you don't. And it's apparent their ridership data supported that Orion would please the vast majority of guests at a reasonable cost per rider, even if a insignificant number of insufferable enthusiasts complain about its similarity to DB.
What percentage of KI's annual attendees do you think complain about the similarity? The overwhelming majority of guests don't think the way enthusiasts do, and thank goodness for that.
"Exceeded" by what metric? Cost? Definitely not, because CF has thankfully learned that it's fiscally irresponsible to spend that kind of money on a roller coaster.
But I can guarantee that if KI could make a clear, compelling business case for a taller, faster, longer, or whatever-er coaster CF would absolutely greenlight it. Fury 325 is proof of that.
