Portable RPG Reccomendation (or just a long, time consuming game)

[2Quick]

Hi all!

This summer I'm traveling  to europe.  looking forward to experience all of the intense history and culture there!

but perhaps more importantly, I'm going to need a game to enterian me for the intense transcontinental plane ride.  That's why I have decied to mine the minds of VG Chartz, to provide me with the best portable game to spend my time with.  I really like RPGs, and this is a unique opportunity to sink some time into an intense one.  In past trips I have made I have used this chance to explore and experience JRPGs that I never would otherwise.  For example, last time I went on a trip I played The World Ends With You, and now is one of my favorite games of all time.  

Here are some games I have considered to play over the trip:

999  (not really an RPG but still on the list)

Etrian Oddyse 4

Bravely Default

Shin megami tensei IV

Monter Hunter 4

Persona Q

Kingdom Hearts Dream Drop Distance

Vrtue Last Reward

If you have experience with any of these games, please let me know you opinion on them.  Any essential DS/ 3DS RPGs I missed? I generally prefer original titles over remasters as an FYI.  let me know.  I am really open to trying something new on this trip, and I want to make sure I make the most of it.  

for reference: RPGs I have played and liked in the past

Chrono Trigger /Cross

TWEWY

Paper mario games/ mario and luigi

Pokemon

 

 

I will create a seperate thread in the future for what games that are only in europe I need to bring back with me...
