From Sega Retro
Dream Information (ドリームインフォメーション) is a monthly promotional mini-magazine/flyer which was produced by Sega for the Japanese market during the time of the Dreamcast. Each issue of Dream Information typically contains advertising for upcoming games, as well as lists of whatever games were being published that month. Some issues additionally feature information on Dreamcast hardware or have small interviews in them. The Dream Information guide also acted as a way to advertise Sega's other services during the time, such as WebTV for Dreamcast, Dream Point Bank, and Dreameye video chat. Around Volume 20 (August 2000), the publication switched from an A4 size to an 8x8" square. This size would continue to be used at the start of the Sega Press switchover in December 2001.
