The Nintendo DS handheld currently has three games that utilize the free 
service: Mario Kart DS, Tony Hawk's American Sk8land, and Animal Crossing: Wild World. The next game set to use the network is Metroid Prime Hunters due in late March of 2006.
From the article: "Outside of Nintendo's in-house games, though, there's little to keep DS owners online. Activision has scored a hit with Tony Hawk's American Sk8land, but apart from that there are no confirmed third-party games from that let DS owners go online."
With such recent success of the free service, why would developers outside of Nintendo be hesitant to use the connection?
