Metroid got the biggest cheers, but the level of gameplay integration for the Wii platform wasn't obvious from the trailer. Super Mario Galaxy 2 looked fresh, fun and well designed for the Wii--Nintendo has really perfected the art of the adventure game over the years and this one is a sure winner. If there's one game I'm really looking to take for a test run, it's Super Mario Galaxy 2.

Other strong featured titles included Wii Fit Plus, Wii Sport Resort, The Conduit, Resident Evil: Darkside Chronicles, Dead Space Extradition, Red Steel 2, Final Fantasy: The Crystal Bearers, Kingdom Hearts: 358/2, COP: The Recruit DS, Style Savvy DS, and Mario vs. Donkey Kong DIY DSi.

Gamers will be familiar with most of these titles and what to expect from them. Two games that had people scratching their heads were Mario and Luigi: Bowser's Inside Story--an RPG that takes place inside the body of Mario's famed adversary Bowser--and Women's Murder Club: Games of Passion, a detective game enigmatically targeted at women aged 40 and up.

The real mystery is the announcement of Nintendo's enigmatic new product: The Wii Vitality Sensor. Nobody seemed to know what it does, including Saturo Iwata, Nintendo's president, who was presenting the product.

The Vitality Sensor is a finger cuff that measures your own biometric data. Applicability seems limited at best. Nintendo did not mention a single use for this new device, although "" and relaxation were used as product buzzwords. Most telling of all were the audience snickers and whispering that accompanied this presentation.
