Who here has played "The Silver Case"? It's a sort of psychological Noir story set in a vaguely cyberpunk alternate version of 1999 Tokyo. It's also Suda51's first real game after working on titles for others before. Masafumi Takada composed its music, which is great.
The presentation is very unique. It's a hybrid visual novel with 3D exploration and puzzle segments. The VN sections also have various other visual mediums incorporated: there are anime segments, FMV segments, live action segments, 3D rendered video segments... it's all very odd.
Despite having been released in 1999, the story has a lot of forward thinking themes- the story comments on how crime inspires people through the media, how the internet makes it impossible to contain dangerous information, how the internet connects dangerous people, the loss of identity in modern society, various Japanese cultural and political nods, isolation in the modern world, obsession with computers...
You should give it a shot if you have a stomach for anything weird.
