BI issues answered... Got it

[Zatoichi]

Can somebody explain to me how BI works? Is it something that you buy to add on to RTW or what? How much will it cost? Sheesh, I'm lost...

Now, I detect a certain amount of sarcasm there... However, I do actually want to know (yes, a whole 3 days before I get the game and find out for myself) where it installs to, seeing as the default RTW directory is under the Activision name, and I'm guessing the BI add on will not live there. So does this mean that unlike MTW:VI, RTW:BI will need to swap disks to play each game? Not a huge issue, but I'm interested by odd things...

Edit: Hmmm - and one of those odd things I find interesting is how comes my quote marks above came out all German? A Hun invasion of the org?
