Enterprise - Role Play Game in Star Trek, released in 1983, was a Japanese roleplaying game that, despite an impressive history of firsts, is not widely known in the western world. It was the first Japanese domestic tabletop RPG. It was Tsukuda Hobby's first entry into tabletop roleplaying games, alongside the wargames that they were already publishing. And as Enterprise was based on an official license from Paramount/Tohokushinsha for Star Trek, it was the first Japanese RPG based on a licensed property.
Enterprise used its own system and had only one product release: a boxed set which included the main rule book, a scenario book (adventure), cards with attributes based on characters from The Original Series (and blanks), and the dice (two percentile, one D6). No additional supplements were ever released.
