Playstats is a utility to analyse the play history on the Wii (shown under Today's Accomplishments on the Wii Message Board). It shows such stats for each game/channel, including total time played, total number of times played, average time played, first and last time played.
Recent updates to the Nintendo Channel now allow it to do much the same thing, often with more stability. However, unlike Playstats it does not display all third party titles and does not give you as much analysis. http://www.toxicbreakfast.com/cgi-bi...=playstats.zip
