This new trailer from The Legend of Zelda: Skyward Sword shows off the Wii exclusive's new upgrade system. Basically you'll find things while fighting enemies and you can use them to upgrade your items to make them stronger. Aside from the Big Goron Sword in Ocarina of Time I'm pretty sure this is a first for the Zelda series, and it's something I'm very excited about. I love collecting things and getting the best items possible, so I can't wait to try this out.
The Legend of Zelda: Skyward Sword is coming out November 20 for the Nintendo Wii. If you want more Skyward Sword details, check out our The Legend of Zelda: Skyward Sword hands-on impressions from PAX 2011.
