I don’t think that any other rides based on DK will suck, but the Boom Coaster would have fit the IP perfectly. Not to mention that it would have been an awesome experience, regardless of whether it was a normal coaster or not. But why wouldn’t you clone the coaster that everyone else is getting, but add another ride to go along with it? You don’t have spacial limitations, you don’t have a small budget, you can do whatever you want.
Also, my biggest question is: If DK isn’t getting the Boom Coaster, who will?
