Nintendo needed a “go big or go home” attitude for their press conference at this years E3 and they delivered in some points and flopped on others. The majority of press conference had Nintendo executives talking about units sold of the Wii and DSi with a small handful of triple “A” titles being announced.

It was clear that Nintendo still had a strong plan to cater to casual gamers, clearly stating there was the opportunity to expand the casual gaming market by, up to, 50 percent in the U.S. and European countries. The majority of the press conference reflected this plan by premiering games like “Women’s Murder Club”, a game will take gamers through James Paterson novels in a mini game laden adventure, and more details on “Wii Sports Resort.”

The jewels of the press conference were the announcements of “Super Mario Galaxy 2” and “Metroid: Other M”, which is made in partnership with Team Ninja of “Ninja Gaiden” fame. Both games won’t be around until sometime in 2010.

One of the oddest announcements of Nintendo’s press conference was the premier of the Wii vitality sensor. A device that looks it should be in a hospital instead of your living room. How willl this new accessory play into gaming? More details will need to be revealed before any guesses can be made.

With the majority of the time at the press conference spent talking about how casual gaming is still a growing demographic, can Nintendo bring back their core audience with the announcements of “Super Mario Galaxy 2” and “Metroid: Other M”?
