Doesnt seem a proper press kit, the steelbook is just from the CE:
For me its more like a promo package. In my opinion a real press kit comes with an art/assets disc and has unique packaging. Sony does this best
If u look other items of this seller, the deus ex isnt a press kit. About the RE:RC i have my doubts, because the patches are in the CE, but u do have unique package, + letter and asset disc.
