The Wii undersea exploration non-game, Forever Blue, sure looks pretty in this trailer. (We have to imagine how the graphics will look outside of a web browser, but we'd swear this game takes at least three Gamecubes taped together.)
While Japan-only at this point, maybe the SCUBA simulation will surface in other regions, with the Wii's success. See the video after the break.
Update: Thanks to readers for pointing out that Forever Blue will launch in the U.S. as Endless Ocean on October 29.
