A couple of similar ideas are kicking around in my head: Journey to the Center of the Earth and Jurassic City<br/><br/>JttCotE would be similar to the books/movies. Basically a team of explorers travel to a prehistoric world deep underground. Players could either be members of the exploration party, the various prehistoric predators, or a member of the various native villages inside this world.<br/><br/>In Jurassic City, about 15 years ago a time portal to the past opened up in a major city, releasing all sorts of prehistoric gribblies into the street. Nowadays, the only people living there are the contestants of the world's most popular game show. Every week a helicopter load of people, either chosen by lotto, or volunteered, are dumped into the middle of the city to survive with nothing but their wits. If they can make it out of the city, dodging killer plants, dinosaurs, and the mysterious saurians, fabulous prizes are theirs. If not, well... Someone or something will sleep happy that night.<br/><br/>So, any interest/questions/comments/suggestions for either?
