Overall, I think 1:1 is a great addition to what the Wii is doing, and Engadget is smoking crack.
However, I agree fully with BenKenobi - It just seems that Nintendo is trying to milk users out of $30 for something that should be intergrated into the Wiimote from now on.
It should be that Nintendo ads it to all future Wiimotes, and then sells the $30 addon, or whatever for current ones to ensure they are 1:1 compatible, so all future titles can use it without partitioning the Wii userbase for a 1:1 only game.
And yes, I promise: if the Wii ever gets a REAL sword fighting, or RPG game using FPS sword fighting that is "real" as in blood, and the like.......I will buy a Wii.
Back from the dead, I'm afraid.
