In some ways, being an Australian is a advantage. Being a +10 on the timeline means we could theoretically be well on our way through the game before the U.S. even checks it out of the store. It happened with Halo 3, I remember well. I completed the game before a friend of mine was even able to get his copy. He was peeved about that. Still got plenty of multiplayer in, though.
But anyway, do you think they'll follow the natural time of day with release, or have staggered times so we all get started at the same moment?
Because if it's the former — you Americans will want to not be looking at the internet in the last 24 hours. Spoilers everywhere.
