In continuing its Wii-prefixed line of accessible game experiences aimed to appeal to all demographics, Nintendo has lifted the curtain on Wii Party, revealed as part of a Nintendo investor presentation.

Think of it as Mario Party with Miis. Miis will carry a central role in the title, serving as an avatar that identifies players. According to company president Satoru Iwata, Nintendo believes this title will fill the void for a “marquee party game” on Wii.

“The developers are spending significant time for this title so that they can include elements that are must-haves in a party game as well as making sure that adequate volume of game play are available,” noted Iwata.

As if you couldn’t already tell, Nintendo’s hopes are set sky high, which isn’t surprising considering global sales of its Mario Party franchise have hit 7.6 million. Capitalizing on the genre further is a no-brainer. Wii Party is scheduled for a release in the company’s current fiscal year, which ends March 31, 2011. Nintendo of America is keeping mum on a stateside release for the time being.
