Good news: I got a response with an apology for Cabela's Big Game Hunter not being processed and a gift of $30 in Amazon promo credit, which is pretty nice considering I sent the game cart-only.
Bad news: I was told that I'm basically out of luck on the judged "Severe Damage" copy of Red Dead Revolver (after I got it back in the mail, I tested it on my 360 and it worked perfectly fine):
I'm considering just letting this go since this is the only rejection I've gotten and I've made a significant profit as is, but what do you all think? I mean, it is $30; should I push my luck and email again or let it slide?
Let it slide.
Now that the great mystery of the Cabela's Big Game Hunter cartridge has come to a close, I feel it's time to start a fresh new thread! See you on the other side!
