Nice going, Wii owners. You've made Mario Party 8 the fastest selling game in the Mario Party series thanks to your purchases over the last month or so. Word from Nintendo today is that the Wii entry has sold over 550,000 copies since its debut on May 29. Nintendo's George Harrison supposedly said that ""Wii users are keeping the Mario Party going strong" which I can only assume means everyone is thrilled to death with the mini-game collection status quo and that Mario Party 9 is probably only weeks away. I hope you're happy. You jerks better buy Zack & Wiki: The Quest for Barbaros' Treasure or I'm stealing the batteries from your Wii-mote.
