Purchasing Questions.

[DarkSoul]

Ok first off whats the difference between the two versions??
I get the basics, but i mean is this.

I can pay $20 and buy Aftershock, then buy a gamecard at EB and use that to play for 90 days or whatever.

So i purchase Aftershock, Download and install it, use the provided key??? the launcher downloads the 3.5 GB of files or whatever.
then i use my gamecard on my account, to upgrade it to paying.


But what if i just use my reserves account, use a gamecard and upgrade...
do i still get aftershock??? did i just avoid paying $20 and THEN another $60 for a 90 day gamecard?? or do i simply get to play reserves and gain more exp.


im not sure how all this crap works and need someone to explain it in lengthy detail.

Why should i spend the $20 for aftershock if i can just upgrade my reserves account using a gamecard???



Also, once the files have been downloaded, Can i burn this to a CD to install later like after i format my drive?? or do i need to use the key and download it again each time i want to reinstall windows??

Ideally what i want is a clean version to burn on CD IE no account info etc...
so it just installs everything then i play.
