I will say this:
I rarely get LE's of games, if ever, but the best I ever obtained was Halo Reach's just Limited Edition and not their Legendary holy moly edition.
That thing alone had this journal packed in it that had tons of well written back story as a character from the Halo universe. Amazing details like coffee cup rings, torn out pages, etc. It was a really believable piece to have, and it looks like a great thing to put up on a book shelf.
With that said Bungie has strictly reserved within my heart an automatic always limited or higher editions on their games from now on. The amount of love and detail they place into things is just unheard of.
I hope that persuades you to the dark side of a Ghost Edition or Limited Edition physical copy.
