The Silver Case is officially coming west for the first time. Get excited.
The Silver Case is a Goichi Suda game that never officially released in English. To resolve this intolerable solution, a remastered version is releasing sometime in northern autumn.
It's rarely discussed, but The Silver Case is an essential and perhaps even the most important past of the Kill the Past puzzle. Kill the Past is the term used to describe a series of Suda games which aren't direct continuations of each other but appear to all take place within the same universe, sharing characters, themes and events. There's a traceable line through Moonlight Syndrome, The Silver Case, Flower Sun and Rain, Killer7 and No More Heroes. This NeoGAF does a good job of rounding it all up, but there's plenty more to explore on the Suda51 Wiki.
More recent Suda games like Shadows of the Damned and Chainsaw Lollipop seem to have no relation to Kill the Past - and were developed with western publisher funding in mind rather than because Suda wanted to make them (don't ask me about Killer is Dead). Now that GungHo is funding Suda's endeavours, we have some hope of seeing the threads picks up again in Let it Die.
