One of the greatest early PS games, the obscure Mad Panic Coaster. You're basically tasked with braving a series of insane rollercoasters while shooting enemies, avoiding obstacles, and trying to stay on the track (you're not attached to it, you have to avoid falling off). The graphics, music, and speed are all great, shame there was never an arcade cabinet.
