Just got my package and the retail disc is nice. Comes with another map/poster and the lettering is embossed to stand off the cover art. There are no codes associated and 2.5 gigs of space is required, so it looks like you just install w/e content is on the disc and that's it. Real question is if you're required to have the DLC disc in the drive or if the normal retail disc will suffice. . .
