Yes, Nintendo DS is for all ages... But so is the Playstation Vita... and the Xbox 360, and the PS3, and the Wii, and the Wii U. I think all of the current gen consoles and the handheld consoles are for all ages. I don't agree when you say that "Games are fun to play no matter at what age you play them" Why? because some games are really meant for adults and some games are really meant for kids. That's why we have ESRB ratings - to determine what age would be suitable for that certain game. Would you enjoy a game of Spongebob Squarepants? Would a 4 year old enjoy NBA 2k13? I don't think so...
