Mountains and gravity aren’t a great combination under normal circumstances, as anyone who’s fallen off a cliff or seen a landslide can attest, but people will play with absolutely anything given half a chance. Find the right slope, terraform as necessary, and suddenly guaranteed doom is an exciting ride and the chance of death or maiming drops to a manageable but nowhere-close-to-zero percentage. The first Descenders was a mountain biking sports arcade game where the object was to ride on the far edge of control, zipping down the trail past trees and rocks at a breakneck pace while sticking to the path only when it was convenient. Speed and tricks built up rep, earning new bikes and other gear, and while it’s a great way to tear up a mountain there are more ways to get to the base than on two wheels.
