In the far future of year 37, humanity has lost their land, their patience, and pretty much all nature. But do they care?
No.
With no land there is little gravity, and chainlifts have become obsolete. Humans always find a way and coasters still go fast. Modern man wouldn't have the patience to wait on a slow ride up anyway, they want to go fast and they want it now. Boosters and launched coasters have become the norm, a piece of cake for modern engineers.
One problem not even the smartest engineers have been able to solve however, is the long wait to actually ride these fast coasters. What causes this? Why does this happen? Noone knows. It just is. People still have fun. Who cares.

[I recreated both Quantum Launcher and the classic Shuttle Loop, but please rate Quantum Launcher as the main coaster since it's bigger.]
[I know the park looks rushed and unfinished in several places, that's because it is. About a third of the park was build in the last 2 days, but a rushed entry is better than no entry. What is there I really enjoyed building, it was fun to go wild for once.]
Original Coaster: Quantum Thruster (LIM Launched Coaster)
