TerraQuest – an “online interactive game [that is] a blend between a mystery and a scavenger hunt.” Launching this fall, it looks a bit like the AI game although I found the trailer to be considerably cheesy. I don’t know how they’re going to limit the game to people over 18, either. But it has a prize of $250,000 so clearly someone gave them some money. By the way, most of the website doesn’t work.
It looks like you have the wrong web site info. The website for the TerraQuest game is http://www.terraquest1.com. You said there was a prize of $250,000. Once I visited the site I saw that there was a $250,000 grand prize and a monthly $25,000 prize. For such a low registration fee and the money I am definatly in!
