A quick check on Game Rankings reveals that Relic Entertainment's Company of Heroes holds the distinction of being the top-rated strategy game, implying that the producer in question is John Johnson. Doing a domain registration check on Exoriare.com confirms Johnson as a contact, along with Company of Heroes lead programmer Drew Dunlop. Johnson and Dunlop recently left Relic, and have likely formed a new studio. Public relations reps declined to confirm Shacknews' speculations on the matter, instead pointing again to Exoriare.com
Exoriare.com itself is password protected. The site can be entered by entring "QUO," the highlighted letters on the front page, into the text field. Inside are latitude and longitude derived from the visitor's IP address (thanks SenorSpine!) as well as what appears to be a visitor counter with an upper limit of 112,112. Upon reaching that threshold, more information may be revealed.
Update: Internet Matlocks over at the Relicnews forums have turned up two additional domains, smokinggungames.com and smokingguninc.com, both of which are registered with the same contact information as Exoriare.com and whose registration information includes the word "Exoriare." Both pages are currently blank, but may suggest the studio's name is Smoking Gun Games. Shacknews' further investigation reveals that "Smoking Gun Games, Inc." was registered as a corporation in Ontario, Canada. The domains were registered in British Columbia, Canada.
