You should pick Popplio. Its final evo is so majestic! Also, wow, those are big games. Those are on par with XenoBlade 3D's 3.5GB.
But you can also play it (Xenoblade) on the :new: 3DS. In other words, the Monado is surprisingly strong with the bathroom.
How would that get me a new SD card? I've got the games pre-ordered digitally, I just don't have the space for it.
...Did I go too far with my comment? Whoops, sorry. >_<" Also, I'm sure your parents would be able to get you an SD card. I recommend at least 8GB.
2) Do you know how many blocks the games are?
