High School Musical. We think a karaoke game would be a big hit with the "expanded audience" out there in the "blue ocean." If we were the type to perform in front of people rather than hiding in total silence, we'd totally play it.
The major problem with High School Musical is High School Musical. If we're going to be singing in a game, we'd rather not sing material from a Disney made-for-TV movie. We'd rather belt out the theme from Night Trap than whatever was written for High School Musical.
Check the link for some new screens. We hope the game is more exciting than the microphone peripheral!
