Man someone should sticky this thread so we don't see another thirty versions of it in the future!
I thought we had this talk a month ago?
The digipak includes material that is not on the Korean DVD cased version (the audio commentary) and has way nicer packaging with exclusive artwork (lots of it too!)
The Korean DVD cased version has material that is not on the digipak (the bonus tracks "Sit in the Mountain" and "Man")
The initial limited version of the DVD cased Terria had a sticker with it, the new unlimited reissue substitutes this for a post card, if I remember correctly.
