Web site Revogaming has been busy compiling data from April 10th to April 23rd to just find out what people are playing over Nintendo Wifi Connection. Here are the Stats…
264,400 unique users a day
Animal Crossing: Wild World 116,901 (44.2% of total)
Metroid Prime: Hunters 70,954 (26.8% of total)
Mario Kart DS 59,544 (22.5% of total)
Tetris DS 15,842 (6% of total)
Tony Hawk: American Sk8land 1,159 (0.4% of total)

As you can see, there are still loads of people playing Animal Crossing, Metroid and Mario Kart. Tetris’s stats are probably because Tetris is more of a Single player game. And bringing up the rear is Tony Hawk: American Sk8land, which is a shame as its a really great game.
