/Is Game Informer only available in the US?
It may be available in Canada as well, although there isn't a specific Canadian option for subscription on their website so I may be wrong.
Both Oblivion and FO3 were unveiled in GameInformer, the international audience didn't have access to the screenshots but their were fan write-ups posted here and elsewhere on the internet very quickly. It's not uncommon for a few people to get their copies in the mail a day or two early so even many subscribers were coming here for information.
