As the not so proud day one owner of the Catherine love is over deluxe edition, I can't really say that it's worth it, even at 50 bucks. Good game though.
I saw a copy of the epic mickey special edition for 30 bucks at the montgomeryville (PA) target. I wasn't really interested and I have to assume that this is extremely ymmv, but I forgot the DCPI. Figured someone might want to know though.
