Chunsoft isn't just known for inventing the Mystery Dungeon subgenre of roguelike RPGs. They're also responsible for the development of the "visual novel" genre: graphical text adventures that focus on telling a story with very little player involvement. Chunsoft calls these Sound Novels, a name they have trademarked.
The company has announced thier latest Sound Novel as a Wii release. Like most other Chunsoft Sound Novels, the "suspense drama" 428: The World Doesn't Change Even So uses real photographs as backgrounds for its text; while early releases featured silhouettes, the later Sound Novels now use real actors as well. Also like other Sound Novels, it has approximately 0% chance of being released outside of Japan.
