What accounts for the popularity of hypercoasters? It's all about popularity, stupid! ;) Look at just about any enthusiast's top ten list and several (I'd wager 3 to 5 for most) coasters on those lists are hypers. They have what it takes to be great coasters: big drops, airtime, and positive Gs. If enthusiasts who are usually more critical of rides than the GP love hypers so much, then the GP must really think they're amazing. When SFNE opened Superman last year, most New Englanders had never seen a hyper, and thought it must be the biggest scariest coaster in the world. A coaster that has that kind of impact on people is sure to be a success.
