You could find a new Mario Party 3DS game in your Christmas stocking this year, since one is being released in Japan, North America, and Europe this winter. The news comes via this morning's Nintendo Direct broadcast, and if you've ever played, seen, or even imagined Mario Party, you know the deal. It's multiplayer competitive minigames.
There are some new twists, like AR minigames and some that use drawing. 7 different boards each use their own rule sets. It's coming out this winter.
