Joystiq reports that 110,000 copies of Mario Kart DS have been sold in the past week, and 45% of those copies have been played online. They note that Halo 2 only managed to entice 18% of users online after three weeks on sale.
It is unclear how many players are finding their way online via home wifi gateways, work wifi, public wifi, and/or special hotspots that Nintendo has established. I wonder how many of these online players are of the “casual” type? I wouldn’t be surprised by a significant percentage.
PS. In case you’re wondering why I haven’t written about the 360 launch — it’s because I haven’t read a single thing worth parroting.
