Nintendo DS' wi-fi connection has some pretty good numbers to show...

According to Nintendo, DS' online service has registered the login of more than 5 million different users and 200 million game sessions! There are 65 different games that support online and the five most popular are Animal Crossing: Wild World, Mario Kart DS, Metroid Prime Hunters, Pokémon Diamond and Pokémon Pearl.

Very good numbers for a service that doesn't even have 2 years clocked up. If you haven't played online, what're you waiting for?
