Ah, the DS...
Mine is broken now, so I haven't played it since January, but I can't deny the amount of perfect memories I got because of it.
Well, since there are so many, let's split them up:
9 Hours, 9 Persons, 9 Doors:
A great game. Storytelling was spectacular, and the mystery tops even Higurashi.
One of the DS' classics, that's for sure.
Castlevania: Dawn of Sorrow:
Among the first games I tried out when I had just bought my first flashcard (an R4 SDHC).
It was short, but absolutely great. Has lots of personality, too, and might have even been my introduction to "darker" games.
The Dark Spire:
This is definitely /not/ the best the DS has to offer.
In fact, in terms of 'goodness', this game might even rank lowest - but that's only because it was never intended to be 'good'.
It was, however, great, and one of the most memorable games I have ever played, in my whole life.
Audio-visually, it is the absolute best.
With a deep, raw soundtrack, and its malicious, dark yet colourful surroundings, this game has managed to create one of the most impressive atmospheres I've ever experienced.
I will never forget that time, when I was deep in the Second Floor with my Thief (Kain) and my Mage (Rydia).
My Warrior (Cecil) and Priest (Rosa) had brutally been murdered mere seconds before,
and I somehow needed to get back to the entrance of the /whole/ dungeon.
With trial and error, I got to the First Floor, where Kain got poisoned.
Crawling through every door, around every corner, and through every battle...it was one of the most intense experiences I've ever had.
The entrance was already in sight when Kain got killed in battle.
Because of sheer luck, and sheer luck /only/, Rydia managed to escape, and I eventually got back to Town.
...where I had to spent all my money to revive everyone. Good times.
This game holds so many great moments.
The Third Floor, with its savage soundtrack and its dark, wild corners...
The Fourth Floor, with its horribly fantastic Garden filled with teleports and turning-around panels...
The first time entering the Sixth Floor; the soft drums quickly making way for high-pitched vocals that combine to make a song that can only be described as 'Epic', the sudden change of perspective, making you feel smaller and more vulnerable than any game has ever made you feel before... Its treasure chests, with the power to instant-kill the whole party even after the battle had finished...
The Seventh Floor, with its Last-Dungeon soundtrack, its gorgeous surroundings, the lights on the ceiling slowly changing colours...Every step was fatal, every single move you make could trigger a random battle, where every Hydra attacked preemptively and could obliterate your whole party with just one of their infamous breath attacks...
Tyrhungs hideout, with the grey-red colour scheme...
The ???-Floor, with its brilliant music, electric-white walls, filled with deadly, otherwordly beings...
There are so many great events in this game.
The young child playing with its dolls in a place whose malice can only be compared with the Ninth circle of Hell...
The one-winged girl, locked up on the Fourth Floor - incidentally, very close to an erotic (stuffed) panda, a unicorn without a horn (=horse), the man with two brains (random guy holding conversations with himself), the invisible man (ABSOLUTELY NOTHING)... the remark made when you enter that place - something about intergalactic beings and space travel - was absolutely uncalled for, but hilarious nonetheless.
The H3ll0 Kitty sign on one of the Sixth Floor's doors...
Gameplay-wise, you might say this is one of the worst-designed games of the DS' library - but for me, it is the very best,
and it is a game so utterly beautiful, immersing, and just all-around memorable that I will never, ever forget it.
Etrian Odyssey series:
My favourite game series. Its memorability isn't as great as, say, The Dark Spire's, but the gameplay is definitely far more balanced.
This game had so many almost-there feelings, compensated by brutal, sudden deaths, and I haven't even talked about forgetting to buy Warp Wires (which only happened twice in total, but /when/ it happened...), the Sixth Strata of the games,
and my very first encounter with the feared, deadly deer better known as F.O.E.
Everything, from the stunningly original Fifth Stratum of the first game, to the purely malicious Sixth Stratum of the third game...
This will always be my favourite RPG series ever to have set foot on the DS.
Nothing more needs to be said.
Final Fantasy IV:
I didn't particularly like this one - it was really unbalanced, far too difficult (even for a The Dark Spire such as myself), and just very vague in general.
However, it was among the first games I ever played that actually had a story at all.
Its characters felt real, the deaths painful.
Though the DS version might not be, from what I've heard, the best, Final Fantasy IV as a game is most definitely a classic.
Final Fantasy: Crystal Chronicles: Ring of Fates:
Together with FFIV, one of my first games that actually had a story - and what a great, moving one it was.
Everything about this game is just all-around great: the story, the music, the graphics, and of course the gameplay itself.
Though less memorable than some of the other games I've played, it is nevertheless one of my favourites,
unlike its absolutely detestable sequel.
Knights in the Nightmare:
In any "greatest DS games" list, this game needs to be mentioned.
It's stunningly original, artistically dark and beautifully complex.
It is, in many ways, a very mature game; not a smile is seen, and not a life is spared.
If you haven't played this yet, you owe it to yourself to do so.
It is among the DS' most original games - if not atop of those - and its beauty will be sure to lure you in.
Pokémon Mystery Dungeon: Blue Rescue Team:
...shut up, you meanies. I love this game. >->
That's probably because of the great times I had playing this with my friends, though.
I'll never forget those.
Rythm Heaven:
Though not as memorable as other games mentioned here, it /is/ extremely original, and just a lot of fun.
I managed to get a lot of gold medals, too. ^-^
Shin Megami Tensei: Devil Survivor:
Yes, this game is littered with grinding.
However, the soundtrack and graphics are great and moody, and its story is among the best, if not /the/ best, of the DS.
I will always remember the final battle.
I dispatched only my Main Character, accompanied by my two best demons, and I fought my way through every single boss of the whole game, every enemy and every spell thrown at me with only these three guys.
That was great. It was fantastic. That battle is my most memorable, and it is an achievement I will always be proud of.
Since I only reached Amane's ending (which is supposed to be the hardest), I will buy the 3DS remake -
not only to reach the other endings, nor to see the 8th day - but also to support Atlus and its USA brethren, for creating and localizing such a great game.
Shin Megami Tensei: Strange Journey:
An absolute classic. The most mature game the DS has ever seen - not in terms of blood and gore, but because of the moral horrors and traumas packed within this game.
Seeing your own teammates, with whom you've fought so long, committing suicide will tear you up,
and hearing them being tortured by demons is extremely unsettling, to say the least.
This game is packed with /so/ many touching events...
Experiencing your own enemies, the demons, getting torn apart - literally - will leave an impression -
but mercifully ending their lives with the single tap of a button is something you will never forget doing.
Seeing a cute rabbit getting skinned and eaten by the adorable Alice was great, too.
I plan on buying this from eBay when I receive my 3DS.
My save file got corrupted at the last boss, so I have yet to see any ending.
The dungeons are definitely worth re-experiencing, too.
The World Ends With You:
What /hasn't/ been said about this game?
It's one of my favourites, too.
The conversations are brilliantly constructed, and, just like everyone else, I cried at the end.
Manly tears, mind you.
Well, that will be all. I've ignored a couple of games I greatly enjoyed, because they just weren't memorable enough for me;
this post is for writing about the memories I will forever retain, and the experiences kept within those games simply aren't part of these memories.
Goodbye, Nintendo DS.
I believe we all have had great times with you, and even when games have ascended into the fifth dimension,
you will forever be in our minds.
Amen.
