Keighn: The description is a little vague on this. The best deal for me was the Deluxe edition bundle then adding each of the small DLCs i saw (since there was no bundle for DLC + wallpapers/music etc). Hoping that covers all DLC.
baronsmoki: Based off of the Steam version, I think it includes all of the DLC
except for the Deluxe Pack:

Hmmm, yeah looks like everything. Just counting the .99 and the 2.99 shows the same number of DLC. When i went to purchase I got the warning of what i already had. Pity the site's algorithm can't check off the DLC bundle as well. These multi-bundle packs sometimes confuse me. Some IF products also include a pack that has everything. This one didn't; it was either the music/wallpapers OR the DLC. Oh well, looks complete.
