There, I ordered Elite Beat Agents and Lock's Quest, and I am trying to find Phoenix Wright on eBay. Hopefully I will have Lock's Quest for when I get my DSi tomorrow.

Oh I forgot to mention in my reply to you, don't get Drawn to Life. The novelty of drawing in characters runs thin rather fast, and none of it changes the very boring platforming adventure game you play through. Lock's Quest is very good though because it combines some very good tower defense gameplay with an adventure/RPG around it.

Ah, thanks. I didn't think the game looked all that exciting, so this only confirms it then

Ninja Gaiden!!

And I found Phoenix Wright brand new for $20, yay! \o/

Whatever you do you MUST buy Pokemon Platinum, since you didn't have a DS before it is perfect for you and try M&L: PiT(Mario & Luigi: Partners in Time) its rather easy but I found it pretty funny and if you want to import the best one is for Jump Ultimate Stars a figther with over 300 anime characters and fun gameplay and Wi-Fi(the Wi-Fi is mainly with japanese because the game only was launched there).

Good choice with Elite Beat Agents and Phoenix Wright. Both are completely awesome.

Phoenix wright has the most compelling story of any game I've ever played. It was like reading a really good book. I got completely drawn in. Never happened with any game, before or after.

Otherwise, the only game I have that is not mentioned here is Meteos. It's an awesome puzzle game, good for at least 20 hours or so, if you are into Tetris like Puzzlers.

I'm holding out for the Gold/Silver remakes to quench my Pokemon thirst, the newer games feel crowded to me, with too many pokemon. Plus the gold/silver remakes should have jumping around in nostalgic joy

And I'm not big on anime, I usually only play fighting games for playing with my friends, so that kind of sucks

Though M&L feels more and more tempting all the time

i didn't think viva pinata was all that good, especially not after playing it on 360...

Ouendan!
