シーマン/ Seaman

Seaman is a virtual pet video game for the Sega Dreamcast. It is one of the few Dreamcast games to take advantage of the microphone attachment. The narration is voiced by Toshiyuki Hosokawa in the original Japanese-language version and by Leonard Nimoy in the English-language version and the face of Seaman is actually that of the game's producer, Yoot Saito.

As a new pet owner, the player is given the responsibility of caring for and learning about the enigmatic "Seaman" species, using a replica of the discoverer's laboratory. The player must figure everything out by themselves, such as appropriate care, with some guidance from the narrator Leonard Nimoy.
