Is definitely worth getting, if you can. You get a CD with the "Original Sound Collection" (10 tracks), a 50 pages book with art and 6 exclusive cards with the characters and their vehicles (Summons?). Oh, and two Square Enix stickers, if it matters.
Over here, the regular edition costs 69,99 euros and the special is only 10 more. Great price, compared to most.
Plus, it's special.
