Don't make the mistake I did. When Steam says I can't install Skyrim until the release date of the game, there is an option to Pre-load the game. I didn't know what Pre-load was but I gave it a crack. Turns out it's a download of the game from Steam and like a lot in Australia I have just a small monthly d/l allowance and crap internet speed. I aborted at 50% and opted to wait to install from the DVD.
So I obviously won't be playing for at least 4 more hours, after midnight. I really don't understand Steam's logic here. Why was Skyrim being downloaded when it could of been installing off the DVD later in the night?
Ack. That svcks. However, if you still have data allowance left, you might as well continue since you're 50% through.
Plus the game isn't that large, really, I think it's about ~6GB.
