This is an odd first post, but I figured if anyone knows the answer, the folks on this site would. (BTW: love the site!)
I recently made an impulse purchase at GameStop, intending to find a game for the DS that I could play with my children. After much debating, I chose a new copy of Magical Starsign, a game that I admit to selecting for its perceived appeal to my 10-year old daughter more than anything. After opening the case and removing the chip, I flipped it over and saw a label that says "Not For Resale" and "Property of Nintendo". I know that there have been a few DS games that were given to GameStop stores for display purposes only and subject to return on demand, like certain Pokemon titles, and they all had the same sticker. Is it possible that GameStop repackaged a sample game and sold it? If so, am I in danger of Nintendo ninjas dressed as Mario and Samus busting into my home and demanding said game? I wouldn't normally worry (Samus ninjas? AWESOME!) except my son, daughter, landlord and fish won't appreciate the intrusion. Plus, the game is not half bad.
