Chrono Trigger is a stunning masterpiece with beautiful pixel graphics, engaging gameplay, fantastic music, memorable characters, and a well-paced, well-constructed time travel story. It's no wonder it's hailed by many as one of the, if not the, greatest video games of all time, and it's fully deserving of such exemplary accolades.
Chrono Cross, its sequel, is fine.
The Silver Case takes place in 1999 in the (fictional) 24th Ward of Tokyo, where the murderer Kamui Uehara committed the titular Silver Case twenty years prior. He's thought to now be harmless, until he escapes from the mental hospital at which he's being detained. We play as the unnamed sole survivor of the unit first dispatched to recover Kamui, who then finds himself swept up into the 24th Ward's Heinous Crimes Unit, which investigates... heinous crimes.
