I know Animal Crossing can be stupid but it just takes it to another level when you play online with some friends.
There was some game I played the other night called Clubhouse Games and it had like over 40 mp games to play even via One Cartridge, from Texas Hold Em to BS to Chess and Checkers and etc, I really thought it was a good game even with the cheesy music ... oh wait all DS games have cheesy music (Elite Beat Agents anyone ...)
Bomberman DS is actually a lot of fun too
