also liked the concept and was credited as someone important to the development of the game. Seaman was intended to be developed for the Nintendo 64DD, but was instead made for the Dreamcast. The decision to develop the game for the Dreamcast was made when he was introduced to the vice president of Sega, Shoichiro Irimajiri, who thought it could make the console a market leader. The prototype was initially developed on a Macintosh computer, with a year-and-a-half spent on converting it into a Dreamcast game. Near completion of the game, test players attempted to use long sentences to play the game. This caused the Seaman creature to say "Can you say that again?" repeatedly. To fix the issue, Yoot Saito changed the phrasing to say, "You talk too long, I don’t understand" in order to inform players they need to use shorter and simpler sentences to interact with the Seaman creature. Localization was handled by Sega of America and spent a total of nine months, where multiple changes to comments were made regarding sex, politics, and slang based on cultural differences. In the Japanese version, the in-game Seaman creature would make comments based on the player's content saved on their memory card but this feature was removed in the English version due to privacy concerns. The creature's personality was different from the English version being more casual and negative. A limited-edition titled Christmas Seaman was released in Japan on December 16, 1999, and available for only ten days either through the Sega Direct online store or as part of an exclusive red Dreamcast pack-in. The title came with two discs, one for sending messages and one for receiving messages, allowing players to exchange Christmas gifts with Seaman. In 2001, Seaman was re-released in Japan for the PlayStation 2 as , the first edition of which came with a microphone. A PC version for Microsoft Windows was planned, with the Seaman being able to interact with the user's applications. No release date was specified, and it was later cancelled.
