No, really. Pre-order the
Dark's Souls Dark Souls Limited Edition now if you're at all thinking about getting this sequel to Demon's Souls. Not only is this an Atlus game, notorious for disappearing off store shelves within the span of a month, but The Limited Edition will also cost the same as the regular edition (only if you pre-order now).
The Limited Edition will feature an illustrated guide book (one can only assume that Dark Souls will somehow be harder than Demon's Souls), a soundtrack CD, "Making of" movies, and an art book.
