Hotel Dusk: Room 215 was a great little mystery game for the DS. Set in a hotel in 1979 Los Angeles, developer CING combined mystery text adventure with a graphic novel style while crafting a decidedly DS experience.
And now it's getting a sequel. Quietly announced by Nintendo, Last Window: Midnight Promise takes place yet again in LA one year after the first game.
It's got a release date of January 14 in Japan, and hopefully won't take too long to break out of the motherland.
