i work at toys r us lemme see if i can help you out lol
i got my ex a DS last year (for no reason) and got her that new super mario bros and Nintendogs (got her the Chihuahua one). Some other ones to consider are Mario Kart DS and you gotta get tetris for any hand held system. DS got a lotta good games tho i might buy one for myself
Presents for ex's are stupid. I know. But they did a remake of Mario 64 for the DS but forgot the name of it. They made a Zelda title recently too. Pokemon Diamond and Pearl would be sweet if there weren't 490 Pokemon. And don't start. The TV show, card game, and memorablia were gay, but it was a great RPG concept.
Mario games are the most popular on the DS I believe. I got a DS too whoopey.
I thought it would be something obvious like "Super Mario 64 for DS." And Pokemon Diamond/Pearl is the 2007 version of Red/Blue. And I know there's 490, because nostalgia made me flip through the Pokemon strategy guide for the Wii game at Best Buy. I immediately saw #463, Lickilicky (Likitung's evolved or devolved stated, didn't get that far) and thought "No f***ing chance," and put it back. Even though it's the first game with Wi-Fi play on the Wii, I'd have to learn 440 new Pokemon (haven't played it since there was 150...152 if you count Mew/Togepi).
