LAN???
On the Wii?
I've tried that with Mario Kart Wii and It didn't work, so I think you should be playing online with the other guys, maybe, don't know if I'm wrong.
Also, the Red Steel 2 swordplay isn't THAT 1:1 don't you agree? I've tried it in France at a show and it didn't felt like I was waving a sword like in Wii Sports Resort.
