I tried the console out today at a friend's house. It was very, very fun.
I played the new Zelda game, something I have been anticipating for a very long while. It was more fun than I had imagined. Like, playing sitting down is possible, but standing up is just like, ugh. It really does feel like you are him.
Sitting down though, you can just get so comfortable. Having two seperate parts you can just have an extra bit of movement that makes playing a different in that you can have your hands at your sides, or on your shoulders, in your pants, etc.
I played Red Steel and Wii Sports, also. Again, playing standing was super.
For whoever mentioned the size of the PS3; the Wii is tiny, picture three dvd cases stacked on top one another. And the sensor bar is invisible it is so slim.
Woohoo Wii! Buy Twilight Princess!
