I have my doubts about Nielsen's data collection methodology here, specifically whether they're able to track games operating entirely within web browsers, also the inclusion of Half-Life 2 almost certainly reflects all games based upon the Source engine and would thus be more accurately labelled as Counter-Strike: Source.
Some interesting WoW tidbits within the report: WoW players average 12.5hrs a week with the game, roughly 2/3rds of WoW players are male, and Warcraft III is disproportionately popular amongst WoW players. Given that, one wonders to what degree WoW is responsible for Warcraft III's continued retention of the RTS crown some seven years post-release.
I don't get the love for Hearts, I really don't.
The report also has a few things to say about those videogaming console contraptions.
