What should I get?

Do ya like sonic? Sonic rush is a great side scrolling sonic game. there are 2 of them.

The kirby games are great too.

If you like dragon ball, and phantom hourglass. Dragon ball origins is actually a great action adventure game, with similer gameplay as PH.

I never played Castlevania, so i can't tell you about that.

I haven't played Dawn of Sorrow, but Portrait of Ruin was amazing. I've also heard good things about Order of Ecclesia.

All three are amazing, Dawn of Sorrow is the best because of the awesome "souls" weapon system.

This is a quality post and I agree with it

The lack of The World Ends With You saddens me.

Castlevania games play with a mix of Metroid Exploration (well, Portait of Ruin and Dawn of Sorrow at least. Ecclesia is very linear compared to the other two.) and a RPG elements are added such as equipment, weapons, items, leveling, and spells.

All the ones on DS are amazing but Ecclesia starts out very slow and kinda boring for a bit, plus it's very linear. Personally I'd say check out Dawn of Sorrow or Portrait of Ruin if you like buddy systems. Plus Portrait has a lot more extra game modes than the other two.

And if you like platforming and action games you should check out the Megaman ZX series as well. If you like a challenge that is.

I recommend The World Ends With You, it's an awesome game and quite different. Lost Magic wasn't a very well selling game but I really like it. You fight using magic which you activate using runes, it's quite good. Professor Layton and the Curious Village can keep you occupied for aaaaaaages and the graphic style is fantastic, a truly lovely game.

I agree with Sakuneko-chan and auS-e-Dude, The World Ends with you is a really great game for the DS. But if you want a platformer, I guess...Hell I just realized I hardly have any. XD Kirby's always a good choice although can be short at times. Well I've heard good things about Castlevania so those might be a good shot.

I couldn't stand The World Ends With You.

Fire Emblem: Shadow Dragon is a solid game, though. It'll certainly keep you occupied for a while. And Castlevania is a must, I should say. I'd go with Dawn of Sorrow.

Yo, Nozama, is Castlevania a good series? It looks and sounds pretty cool and Im thinking of trying it out.
