UPDATE: I've decided that these are most certainly fakes, and I'll not be buying them. Thanks for all the quick help guys, you rock 
So, I found a guy selling 5 GBA games for $15 on craigslist, but after looking at the picture, I'm suspicious about if these are authentic games or not: http://bend.craigsli...2983047534.html
Notice some of them are a lighter gray, and for me the biggest giveaway is the middle game has an RP sticker on it. They can't release a game without a rating and just leave it RP, can they? Should I buy these or just pass?
