The actual contents of the USB is a bit funky! They seem to have used an almost 60GB USB stick, and filled a chunk of it up with including the game three times, twice in zip files and once in a folder!
This seems... an odd thing to do.
I noticed also that the Windows DVD (although not the USB) has this random extraneous shortcut file sitting in the folder
IDK, I guess it seems a bit careless? Especially combined with the kerfuffle around the Loom USB!
