Meh, let's be honest, a 16GB card can easily fit enough stuff to keep you busy, with 32GBs or more you may be able to have a ton of games installed at once, but you are never even gonna touch 90% of them anyways, so what's the point other than having slower loading speeds? I have both a 16GB and a 128GB card for my 2DS and have found out that I use the 16GB card more since all the stuff I play is only around 12GBs
I get what they were trying to say but what the ad actually says is "we tried to cram a ton of features into the iPad but all of them got irreparably mangled
in the process."
