It'd be good if it was based around a roulette game, where all passengers face outwards and there is a red light in front of them (in the dark) and the light spins around everyone until it gets slower and slower, then it stops suddenly on a person and they drop on their own then the light moves around the carriage dropping each passenger, the suspense would make it SO scary.
That's such a wicked idea! I'd love to see that - That would fit perfect in Las Vegas. Maybe they could update The Stratosphere Tower Big Shot!
Back on the idea of having one at Alton Towers - I really cant see this working. They'd never get the permission for one - The only place I can see that it would fit, would be in X Sector, but then Oblivion is already there, so I doubt it would work.
As much as I love drop towers, I think they are a bit out-dated now. The only way to get a really exciting one, is if it's something new and different. Apocolypse did well when it opened.
. Or if it was really really high. How about one the size of Kingda Ka!
