I'm still playing Bravely Default on my 3DS which is why I havent gotten to Paper mario yet - I do plan to play TTYD before I play the 3DS one though which is soon :P.
lol. i got bravely default as well (actually i pretty much have every 3ds game thats worth owning), and thats one i havent touched at all yet. paper mario was the only game i ended up playing out of the games you listed. bravely default feels like it would have to be a huge investment. one i havent been willing to make yet. TTYD is a massive game. that one should take awhile. if you plan on 100%ing anyway.
