Volcano's already been done before, and it's a pretty cool game to boot.
I was really looking forward to the theme Highway had planned before. My wife (thank christ) and I both agree that the 'new' pin space is sorely lacking in more adult themes. And I'm not talking about the "porno" games, but there's definitely a place for adult humor and art style out there. Just going to take a company with balls to do it. Guess we'll see how Nordman's table for Multimorphic turns out.
