I originally picked up Costume Quest because I thought it would appeal to my wife, but have recently started playing it myself (seeing how I was wrong).
So I've been running around Auburn Pines beating monsters and collecting Creepy Treats. So far, I've managed to trade all of my redundant cards with kids I met around the neighborhood, with the exception of an excess Swedish nose.
Since I highly doubt that I was simply lucky enough to pick up duplicate cards that the other kids just happened to need, I suspect that the cards collected are in fact predetermined. This leads me to believe that I am supposed to do something with that spare nose, and I don't want to miss my chance once I go through the gate that opened now that I have trick-or-treated all of the houses.
So am I reading too much into this, or is there some kid I missed that I could trade the extra nose with?
