I recently bought the 3DS and i want to buy some rpgs for it
so, which is/are the best, rpgs available for Nintendo DS?

Great news Robo , your in for a treat especially xenoblade , not so much , the last story , so one great game and one slightly above average one , don't get me wrong LS is Ok  but  it's no Lost Odyssey.

Xenoblade is awesome one of the best RPG´s I´ve ever played.

But come on FF XII-3 really wouldn´t rather a totally new Final Fantasy like Final Fantasy XV. I mean aren´t sick of Sequels from Sequels. I really liked FF XII and I loved Lighting my Favourite Final Fantasy Character ever. But wouldn´t be cooler to see a whole new setting new cahracters and completely new story?

@mjk45, thanks for your opinion my friend.
btw my companys 1st game will be shown off, if everything goes to plan at tgs this year.

Glad you enjoyed ME , about the ending , one of the problems I had with it  was they weren't fleshed out enough ,  I know they said they are going toexpand on it , but you want that kind of information then and there not tacked on  later , because after all there you are at the culmination of a fantastic journey and you want to know there and then what it all means in the wider scope of things , another thing is for a game about choices you got very little at the end , just lots of questions without answers  , also and this isn't there fault most  games when they end leave you some what wanting , but for the good ones it's usually wanting more , in ME's case , to me anyway I want more but they by making it at least look like the galaxy wide community is gone  along with the relays,  the light at the end of the tunnel looks dim in regards to future adventures post ME , sure even though there's lots of room for pre ME1 adventures I also have a feeling some of the  people deep down wanted like me a scenario that makes  for a ME4  , relays and all with maybe a rebuilt/building citadel , that continues on the further endeavours of Shepard in a changed milky way dealing with the aftermath and all the fallout of devistated home worlds resurgent races e.t.c .

Available for NDS? The original DS? or do you mean 3DS? If you mean original DS, then there is too many too count, but some great ones are Shin Megami Tensei: Strange Journey, and the Devil Survivor games as well as Chrono Trigger, Golden Sun, Radiant Historia, The World Ends With You, some Final Fantasys, some Dragon Quests, some Pokemons (though I'm personally tired of them), the Etrian Odyssey games, and a ton others. Of them, I personally love Strange Journey and the Etrian Odyssey games and Chronot Trigger.

But if you are specifically referring to 3DS games, then there isn't a whole lot at the moment, but Tales of the Abyss is phenomenal and definitely worth getting! Also, the expanded version of Devil Survivor (Devil Survivor Overclocked) is great too.

P.S. On the topic of Final Fantasy, I'd also love to see FFXIII-3 at E3 though I'm kind of expecting TGS to be the earliest we'll see it. But I would love to see FFXV, ESPECIALLY if Hiroyuki Ito is the director.

Please Top 5 rpgs for DS

No one can give you a definite Top 5 RPGs for the DS, mostly because every list will be subjective. If you want a top 5 based on my opinion:

1st. Dragon Quest IX
2nd. Dragon Quest V
3rd. Etrian Odyssey (any 3 of them)
4th. The World Ends With You
5th. Pokemon Black/White

If you want a top 5 based on metacritic rating:

1st. Chrono Trigger
2nd. Mario&Luigi: Bowser's Inside Story
3rd. Castlevania: Dawn of Sorrow (Action-RPG/Adventure game)
4th. The World Ends With You
5th. Pokemon White

Top 5 Gamerankings:

1st. Chrono Trigger
2nd. Mario&Luigi: Bowser's Inside Story
3rd. Pokemon Soulsilver
4th. Pokemon White
5th. The World Ends With You

Probably any other user here will give you a different top 5 as well.

ACTUALLY, if yer have a good ammount of Friends also into DS-RPG's, i'd recommend you Phantasy Star Zero!

Its a Spin-Off of Phantasy Star Online (NOT Episode 3! a good game in its own rights, but i highly prefer Episode 1+2 and Blue Burst.), an MMO that was released like a decade ago. I played it together with Friends for over a Year, with almost 1000 Hours of Play. (600 with my Main Character)

PSZero is the "light" Version of its older brother with some cuts that really hurt the longevity, but still, its an amazing game, easilly one of the best looking 3D-Games on the DS, and - given the System its released on - its quite huge.

Anyone in here who has played/finished the "Rainfall-Three"? (Xenoblade, TLS, Pandoras Tower)

If so, what are your opinions to those games?
i play Xenoblade right now, with TLS following early next month. I think Monolith really created a great game there, lots of stuff to do, a good story, refreshing battle system (almost MMORPG-like,.. or, instead, think of White Knight Chronicles II and FFXII making a Baby lol) that actually WORKS, and beautiful environments.
i didnt regret dusting off my Wii for it so far, i am around 40 Hours in.
