With all of the science fiction wargames that were published in Japan, almost all were based off anime shows, and none used original designs (and heck, even the US Battletech just used robots from JPN anime shows without permission to begin). This one does use its own story and designs.The game includes 4 mounted maps, and many scenarios that e are each given their own scenario cards (ala the US Squad Leader wargame). Includes slightly larger counters than are usually used in Japanese wargames.There was an expansion/sequel to this produced. - BoardGameGeek
