That's the thing... I used to be a diehard Warioware fan, but I was also a diehard pokemon fan.
_{I've never really had to think this much about buying a game. IT'S SO STRESSFUL!}

If you've ever wanted to create your own microgames easily, D.I.Y. is perfect, but you would have to put some time into making each one. On the other hand, if you don't want to or can't put in much time into creating microgames, then HG/SS is good, but it would probably take the same amount of time. Considering you like Electroplankton so much creating music, D.I.Y. would be perfect for you. HG/SS is basicly buffed up remakes of Pokemon Gold/Silver, and if you've played those and still own them then it might not be the best idea to get HG/SS. However, Pokemon Gold/Silver were the best Pokemon games except Red/Blue. I might get SS for easter (my parents asked if I wanted a DS game, and I already bought D.I.Y.) and if you can wait until then I'll give you my opinion, but I can say D.I.Y. is basicly a good warioware game plus a game creator. That equals a great game. The only thing that might bother you about D.I.Y. is that all of the controls are tapping, no buttons.

Just want to let you know, saying I'll like a game because it's minutely similar to electroplankton isn't really helpful.
I have now decided. No offense, but you didn't really influence me at all. What influenced me was the fact that SS is $5 more than D.I.Y. If I save up 5 extra dollars in a week, then I might get SS. Otherwise, I'm going for the slightly cheaper D.I.Y.

I need suggestions...

Which DS Castlevania should I get? I"m a seasoned Casltevania player, and I don't care about the art style that much. I know Metacritic says Dawn of Sorrow is the best, but part of that is because it came out before the other games.

@R-L-A-George The best fighting game is Bleach: Dark Souls.

I second the request from moomoo -- i've been on a Castlevania kick lately with ReBirth and Rondo; wouldn't mind a good handheld Castlevania as well. I tend to prefer the old-school Castlevanias over the "Metroidvanias", but i'm not averse to the Symphony-style games.

I have no idea.

If you're willing to import, get Jump Ultimate Stars. Otherwise, get the Bleach game.

If you mean an action game, Ninja Gaiden: Dragon Sword is quite awesome.

Tetris and Meteos are musts, but Might and Magic is fun too, even if it's more strategy then puzzle.

The World Ends With You is by and far the best RPG ever created, let alone on DS. If you want something more traditional, go for Bowser's Inside Story or Super Robot Taisen OG Saga: Endless Frontier.

I have no idea.

From what I've heard, Glow Artisan and Mighty Flip Champs are fantastic.

Haven't played any of them, but I hear Naruto Shippuden: Ninja Destiny 2 is the best. Although, according to metacritc, Naruto: Path of the Ninja 2 is the best, with a 62 average.

I'm starting to lean on Order of Ecclesia now. It's by far the hardest of the 3, and that's appealing enough to make me buy it. I know all three are worth buying.

I'd love to import, both Jump Stars games. But on amazon they are a massive 60 to $100 or more, separate.(I dream)

You've made some pretty good suggestions.

What are some cool 3D (not top down) games for ds?

There are lots of 3D ds games with different genres but Here is what I could recommend to you:
FPS:
Metroid Prime Hunters - (Great for local or online multiplayer, though single player campaign is decent with great exploration)
CoD Mobilized - This is the best of the 3 ds CoD games out there because of online multiplayer.

Survival horror:
Dementium the Ward - It is essentially a FPS style Silent hill game. While the game is not perfect, I still strongly recommend this game to survival horror fans. Watch out for the sequel coming out this may.
Resident Evil - (I consider this game 3D even though it has pre-rendered backgrounds) the controls may feel wonky at times but that wont stop you from enjoying the game's classic/creepy atmosphere, retro zombie shooting action, clever puzzles, and the hilarious voice acting (ex:"You were almost a Jill sandwich!")

Platforming action:
Super Mario 64 DS - another classic remade to the DS. If you can get past the awkward controls(D-pad instead of analog nub), you will truly appreciate this game for the levels, bosses, music, secrets and minigames.
Ninja Gaiden Dragon sword - (this is a 3d game using pre-rendered backgrounds) Pure ninja action controlled by the stylus. It may be short, but it has good replayability with different difficulty settings and other unlockables. If you prefer a button controlled game, this game is not for you.
Transformers the Movie DS - this a sandbox/mission type game similar to a 3D GTA with giant robots. It may be decent to some, but If your a transformers fan or if you like a gta style game with transforming robots, you may consider getting this.
Crash Bandicoot Crash of the Titans - Its a decent crash bandicoot game compared to the earlier games, but it is still fun you can unlock more combos and even take control of your enemies.

Wow that's awesome! Thanks for all the help. I'm really intrigued by Modern Warfare Mobilized mostly and Dementium! So yeah, cheers for the recommendations.

Should i get contra 4?

I saw it at a store for only 15 dollars new, an I have heard some peoples opinions, but I want to be sure before I buy it. So what are peoples opinions on the game? And I also kinda want it for the nes contra games so are they ported well or do the controls suffer?

I'm still not convinced that any FPS is good on the DS. Portable FPS in general are suspicious to me. I've heard Metroid Prime Hunters and Moon are good but I never did enjoy the controls for Metroid Prime Hunters.

They work fairly well, better than using a stick, but damn do they cramp up your hands faster than much other choices out there.

Devil Survivor or Strange Journey? I can't pick >_<

Ok well I just recently started to have to take a half hour bus/train ride to work each day, so I decide to dust of my DS. Now I only have the original Model DS, (I am really not that interested in the DSi since I cant play any of my GBA games on it) and one DS game which is Castlevania: Dawn of Sorrow.

I can really use some suggestions as to some other games. I am looking for some platform games like Dawn of Sorrow, My friend suggested the Megaman Zero Collection but I have never played any of them. I am opened minded to pretty much any game out there. Are the other Castlevanias any good??

Thanks in advanced.
