A unit entitled 'SG girls' was formed and numerous events and concert were held. Advertisements and articles were placed in many magazines such as Dengeki G's Magazine as well as the TBS radio show Sentimental Night which aired in 1997.

At the time, many of the staff and cast were unknown by the general public, which spurred a large media sales campaign designed to widen the game's exposure and establish it as a new brand. While the six central characters were cast by Seiji Productions, the remaining six were considered unconventional for the time in that they were selected for public appeal. įollowing the 1994 hit success of Tokimeki Memorial, NEC Interchannel initiated a cooperation between Tabeta Toshio and the main staff of the Graduation series with game production house Marcus in an attempt to produce a 'Tokimeki-like' game. Its nicknames amongst fans are typically Senchi or the contraction SenchiGura. Several dojin games have been made based on the characters, including the infamous Sentimental Shooting scrolling shooter, which combines a very engaging (and difficult) shoot 'em up with provocative imagery. A number of non-broadcast Japanese audio dramas have also been produced.

Three Japanese radio dramas based on the series, titled Sentimental Night, Kaettekita Sentimental Night, and Only Sentimental Night 2 were produced. An anime television series based on the series was later produced, titled Sentimental Journey. Sentimental Graffiti ( センチメンタルグラフティ, Senchimentaru Gurafuti ) is the name of a dating simulation series by NEC Interchannel.
