No weekly PC sales charts this week. No, we got monthly sales charts. Specifically, for the month of July, a period dominated by AAA PC exclusive Nancy Drew: The Phantom of Venice, which lived up to its pre-release hype by taking out the top spot. It's followed by...yeah, pretty much everything Maxis and Blizzard have ever put out between them (though Civ IV at #12 should warm a cockle or two amongst you).
