I bought an Animal Crossing game for my Nintendo ds a few months ago, and I am beginning to think it's a fake (off Ebay, figures.) However, there are signs that it is real, and signs that it is fake. First of all, the game case is clear and it is thicker than my other game cases. The cover picture looks fuzzy, when my other games have sharp, crystal clear pics. The instruction booklet cover is dull, but it has instructions inside it (I heard that if it has a long game review by Gamespot in it instead, it's a fake.) The actual game cartridge's cover sticker is off center, like it's just been slapped on there, when my others are perfectly aligned. However, it does have a unique code on the back below the Nintendo seal and the patient pending crap, which obviously means it's real. It freezes a few times a day when I'm playing, and I'm tired of getting Mr. Ressetti. Also, I got a brand new dsi yesterday, and it won't work in that, just my lite. Please help thank you is it real or fake?!
