Read the whole list properly before voting - there are a lot of choices.

I don't even feel worthy of voting because I've only played a few of these. You're right though, RPG is my favorite DS genre.

I haven't played the majority of these, but it boils down to Chrono Trigger and Devil Survivor for me. I'll go with Devil Survivor because I've spent way more time with it.

I chose Mario & Luigi: Bowser's Inside Story. That along with Pokemon Platinum are the only games I've played from list.

I don't think there is an SMT:Devil Summoner on the NDS.  You must mean Devil Survivor.  Devil Summoner was released on the Sega Saturn in 1995 and remade for the PSP in 2005, though I don't believe it was ever localized in English.

i have to put pokemon soulsilver. it's probably my favorite ds game.

M&L: Bowser's Inside Story easily!

Of those I have Pokemon Platinum, Shadows of Almia and Heartgold, Chrono Trigger, Final Fantasy III & IV, Luminous Arc I and II, Shin Megami Tensei: Devil Summoner, The World Ends With You, FFTA2 and Crystal Chronicles. Some of those I haven't even thought about playing, let alone finishing. It's a super-deep lineup, and I wonder how I'm going to find time to scratch the surface of all those games. 
Anyway, my vote goes to SMT: Devil Survivor because I enjoy its presentation and storyline the most of the games that I've played so far, and the SRPG mechanics are addictive and solid. I don't really like how the difficulty starts to spike near the end, and there's also only one save slot so you can't opt out of a hard storyline path and try an easier one.  
I'm looking forward to the Golden Sun remake, as I missed that on the GBA. This list is only going to get longer...

Mario and Luigi

Devil Survivor was great

World ends with you just beats Devil Survivor for me. 
Completely blew me away with the design and soundtrack. 
Does there really need to be 7 pokemon games on here? Pokemon Ranger and main pokemon series split. The rest are just upgrades of the same basic game.

There's a lot. Devil Survivor probably my favorite, though. Dragon Quest V would be in there, World Ends with You, Bowser's Story, Final Fantasy IV. The DS has been great for old school RPGs.

MASSIVE LIST

I haven't played but a fraction of the ones listed above, but I voted for Dragon Quest V: Hand of the Heavenly Bride anyway.  I've been pushing that game for more than a year now and it's even on my "All Time Best" list here on Giant Bomb.  I just love the conversations and remarks that your party makes throughout the game that sets it apart from most other RPGs on handhelds.

Final Fantasy IV - the whole remake just blew me away, even if the balancing was a little iffy at times.
 
I also own:
Final Fantasy III - Got about halfway through before conceding defeat
SMT: Devil Survivor - Still stuck on Belder...
Kingdom Hearts 328/2 Days - Finished
Disgaea DS - Only a few chapters in
The World Ends with You - Finished
Pokemon Platinum - Finished
Luminous Arc - Barely started
Mario and Luigi Partners in Time - Barely started

Although I have a backlog of a bunch of these, right now I'm playing Dragon Ball Z: Attack of the Saiyans and I love it. It's really fun.

How many of those have you actually played though? "

Why make HeartGold and SoulSilver separate entries?

I don't have a DS, but Heart Gold has to get my vote.

Definetly The World Ends With You or Chrono Trigger. I voted for the latter, but both are just as equally great and should be played by any person who says they're a RPG fan.

The World Ends with You is genuinely and honestly probably one of the best JRPG's ever made.  I felt like a wide-eyed 15 year old playing FF7, a weird feeling of wonder I haven't gotten in decades.  All this despite the small screen.

You missed playing the original Golden Sun? Pick it up from amazon and find a way to play it. It's too good to miss. "

Well, get a DS and play the game dammit.  Then you will be AlwaysHappy. "

I voted on Chrono Trigger.

" Look at my Avatar.  Which game is he from.  There's yer answer. "

I question Fire Emblem being on the list, as it's more of a strategy game with some RPG elements. I voted for it anyways, because semantics, shemantics.

Shin Megami Tensei: Devil Summoner takes my vote.

All I know is that Lunar: Dragon Song is the second worst RPG I've ever played, on any platform. :P

I'd rather play Unlimited SaGa than Final Fantasy X-2.  I know this because I've put time into both, and Unlimited SaGa is far better.  As for the poll, I'm voting Strange Journey.  God damn, that game is awesome. "

Really?  I actually liked X-2.  I played that a fair bit and found it to b better than okay, whereas 30 minutes of Unlimited Saga and I was sure I had slipped into a parallel universe where Square Enix RPGs were complete shit.   "

Final Fantasy X-2 was just godawful.  It is one of the single worst games I have ever played in my life, from its complete bastardization of the characters and world of Final Fantasy X to the insane 100% Completion requirements to the fact that the 100% completion ending is not worth the time and effort it takes to acquire.  I have a friend that actually finished with 100% completion, and she wants every one of those hours of her life back.  Me, I couldn't stomach it enough to even come close to finishing it.  The only thing I like about X-2 is the piano music that plays over the opening credits.  Everything after that causes my mood to swing from basic disgust to a desire to slam my head against a wall to make the hurting stop.  That game is garbage. "

Chrono Trigger since I hate random encounters and have a pretty entry level appreciation of RPG's.

I knew it was dislike by many, but man, you hate that game more than a Republican hates Obama.  I think you need to start a list of people who worked on that game and eliminate them one by one, just to ease your anguish.  I will be able to play that game again without thinking of you. "

Well, based on time spent playing I would say the Pokemon games...by VERY VERY FAR. But my favorite DS RPG was probably Chrono Trigger, awesome game. I actually wished it was longer by the time I finished it because it was so much fun. Playing FF3 right now, need to get FF4 and Mario & Luigi sometime soon. Should probably play The World Ends With You at some point also. But yeah, haven't played A LOT of those games.

Need to finished the world ends with you but ill say best rpg on DS.

My true desire is to one day upload a Youtube video of a copy of the game being destroyed in an explosive fashion, but I don't want to waste my own money on even a used copy of it. "

" It is Chrono Trigger, but It's soon to be Final Fantasy Gaiden. "
