Pink XL is a limited edition but it's not really hard to find/get. They released it for Christmas and re-released it for Valentine's Day so they might do it again. It's a nice color but don't get it just because it's limited edition.
In addition to all that has been mentioned, you can't go wrong with the Mario platformers (and Mario Kart 7). There are also plenty of good games on the eShop worth checking out. --- Them ain't your funyuns, them's Foxxy's funyuns.
