I'm about to get a DS and am having trouble deciding which game to get.  I'm thinking either Zelda, Dawn of Sorrow, Phoenix Wright, or Professor Layton.  My friends already have Super Mario and the AW games, so I can just borrow those.  I like Castlevania games, PW seems fun, and I used to like Zelda, but I haven't played a Zelda game since Ocarina of Time.  Any thoughts?  Oh, and what's the difference between Ace Attorney and Justice for All?  I've found Justice for All for like 10 bucks, but the lowest I found AA for is 22.

Ace Attorney is the first game in the series and has a DS only case at the end of the game. The PW games are all ports of gba games only released in Japan but they're one of my favorite DS series. As far as Castlevania goes i liked Portrait of Ruin better than Dawn of Sorrow but there is also a new one coming out soon called Order of Ecclesia. Zelda and Layton are also very good. Any of the games you listed are a good pick, it just depends what type of game you want to play.

Well, if anyone's curious (and I'm sure everyone is :p ).  I ended up getting Hotel Dusk because a friend of mine said that he could lend me PW, so I figured I would check this out because it seemed really interesting.  Now just to wait for my DS to arrive from Amazon...

Final Fantasy IV

Tetris DS.

I've been playing Zelda on the DS for weeks now and I would recommend it.  It doesn't matter whether you've played the newer games or not as it's a separate story.

Elite Beat Agents...my guiltiest pleasure.

Castlevania: DOS is my favorite DS game...and Professor Layton is a great game too.
