This game is a remaster of "Advanced Daisenryaku: Deutsch Dengeki Sakusen", originally released for the Sega Mega Drive. Daisenryaku is not a series owned by Sega, but the Mega Drive version of this game was co-developed and published by the company, meaning it qualifies for the Sega Ages 2500 series. Despite a graphical and audio update, little has changed in this release, and none of the upgrades in game's many sequels were put into this version.
