Phoenix Wright is my personal favourite on the system; I never liked graphical adventures, in fact I despised them, but this game certainly is a LARGE exception. Brain Age is a game I like because it's always a game that people want to play, it's fun competition. As Zeus said though, there are a lot of titles already available, and they're all for a good price.
Accessories: Obviously lots of cases and stuff, I just keep my stuff organized on my desk.
If you're into portable movie stuff, there's a media center with a 4GB hard drive which costs , and also a media dock which uses 1GB or 2GB flash cards You add various music file types, various movie file types, photos, software, etc... Though personally, I find the whole portable movie thing to be more novelty than anything (I have a portable DVD player from a few years ago and I've maybe used it 3 or 4 times total); but that's just me. All of this is by Datel.
Also, DS will soon have access to updated remade versions of Final Fantasy 1-6: already GBA versions of 1, 2, and 4 released; 5 and 6 will follow on GBA; The former NES FF3j has been completely remade in 3D with some additions to dialogue (story will be relatively the same. Dialogue, for character development purposes, has been re-written) and cutscenes, as well as advancements in gameplay. Those aren't the only RPGs, in the next year, between DS and GBA there are about 30 RPGs coming out (mostly on DS which looks to be RPG developers system of choice now over the GBA format). Most RPGs set for release from here on out are DS, but as a whole, DS RPGs really just started coming out recently. Skip the Lunar game, that came out about 7 or 8 months ago, though. =)
The DS RPGs I am most looking forward to are: ASH (an awesome looking Sakaguchi game) Xenosaga Episode 1 and 2 (the story told as it was meant to be told), Tales of the Tempest, Final Fantasy III, Contact, Rune Factory, and Baten Katos DS. The GBA RPG I am most looking forward to is Final Fantasy 6 Advance. There are two RPGs coming out tommorow on GBA from Capcom, both Mega Man related. If you are into games like Secret of Mana, then it might be in your interests to check out Legend of Mana and Crystal Chronicles, for DS, as well.
Of course, there are awesome, big name, non-RPGs coming out which include: Spore, Zelda: The Phantom Hourglass, Phoenix Wright: And Justice for All, Starfox: Command, Catlevania: Portrait of Ruin (which looks WAY better than any Castlevania game released since Rondo of Blood back in 1993), Black and White, etc.
For the past 7 or 8 months, the only system I have bought games for is DS (well, GBA as well, but I play them all on DS. I have also bought several really cheap PC games, none with a price over $2.). Though I do plan to start up with Consoles again later this year with Xenosaga Episode 3, Final Fantasy 12, Red Steel, and Legend of Zelda: The Twilight Princess. As I see it though, the DS will probably remain my main system for at least the next year and a half. If you couldn't already tell, I am in love with the system =)
As for DS Lite, I will get one when it comes out in a darker colour: I have had my eye on the enamel blue since the system was first unveiled.
