Some of you might have seen the fansite set up by some fans at falloutnewvegas.com, which, while understandably lacking in content, had mostly the #1 spot in Google searches for Fallout: New Vegas. However, as of October 5, the site has been shut down. According to registration data, the domain is now registered with CSC Corporate Domains, Inc. As it turns out, so is bethsoft.com, zenimax.com and other domains owned by Bethesda Softworks/ZeniMax Media.
Honestly, I was surprised that Bethesda had not registered the domain on the very day they announced the game, and them taking the domain over from the fansite now is simply them protecting their trademark. The fansite will likely be free to continue at some new address.
