A few thingsMore horse power the new 3 DS is stronger than an old 3 DS . While a few games do make use of this , this will probably be something you only really notice on startup . There are a few games that will ONLY work on the new 3 DS , but last I checked , it was less than 10 . Face tracking 3 D the new 3 DS uses it ' s inward cameras to track your face and move the screen so that no matter which way you ' re facing , the 3 D effect should work for you . Pretty much everyone seems to have a positive experience with this face tracking , so I ' d say it works pretty well . Built in NFC reader instead of needing an external NFC reader , the new 3 DS has one built in . Pretty handy if you like amiibo and games that use amiibo , but otherwise not too great . Second analog stick there ' s now a second analog stick on the right of the 3 DS though it ' s more of a nub , similar to what you find on laptops . It helps , but the number of games that utilizes it is kind of small , from my understanding . That ' s pretty much it , feature wise .
