I asked for Mario and Luigi: Bowser's Inside Story, along with Yoshi's Island 2 for the DS this Xmas, and I got them both. However, my mom found them through a seller in Hong Kong on Ebay, which is questionable . . . The games are in clear plastic cases instead of the black ones, and the outside looks like a VERY good photo copy. Both of them contain pamphlets, but I don't think they are the real deal. The Yoshi's Island pamphlet has nothing in there about play controls or anything like that, but rather what seems to be a drawn out review of the game (can somebody verify what a REAL pamphlet was like?).
Also, neither game came with the code that you can enter at Club Nintendo. These games BOTH should have came with it, right? Since they were Nintendo products. If you have the game and can take photos of the pamphlets, it would really ease my mind to know if these are in fact bootleg knockoffs. The games seem to work fine in my DS, so I shouldn't be worried, but I am somewhat of a purist and don't want to buy bootleg items. I like to give my money to the company that developed and worked on it for months, and not a thief that stole a code and put it on a blank DS card.
