Some of you may already know this, but I spent 2 days this week at Nintendo of America headquarters playing The Legend of Zelda: Twilight Princess for the Nintendo Wii.
I'd tried the system out at E3, but was only testing demos for a few minutes at a time. About 9 hours of actual playing taught me a lot more about the controls. I was surprised by details like the Wiimote not sensing the "thrust" of a sword, but impressed by the possibly perfect ergonomics of the controller.
If you haven't yet, I urge you to check out my post over on Kotaku. It specifically only covers my experience with one game, but should give you a better idea of what the Wii gameplay is really like. If you have any questions about the hardware after the read, that's what comments are for.
