I mean what actually happened was Great Adventure wasn’t supposed to get anything for the 50th anniversary and ride fell into their lap. Considering the rumors that they were planning a Giga and it got cancelled because the new CEO believed the best way to revitalize parks was to no longer build thrill rides, they took what they could get. Then, corporate realized that destroying Kingda Ka meant the park needed a tall replacement and they weren’t willing to spend money on a 350ft+ coaster that was full circuit, since with inflation and tariffs this coaster will probably cost about the same as Ka did. I doubt they are just deciding to build only shuttle coasters in some grand conspiracy.
Correct me if I’m wrong, but project purple will actually be the only extreme shuttle coaster Six Flags or Cedar Fair have purchased directly from a ride manufacturer in the last decade or so (aquaman and gold rusher were both originally purchased for other parks if I remember correctly)
That being said, I am kind of rooting for the next addition to be a family boomerang in a revitalized kids area because it would be pretty funny
