Yeah, I've got the Wii version, since it's the only current-gen console I own. :) A lot of people rip on the Wii version mercilessly, but I like it (though I could do without the "need a Wiimote for EVERY INSTRUMENT" thing--I only have the one guitar, but if I pick up a USB mic at any point, it means I can't do double duty on guitar and vocals, because I only own one Wiimote. -_-#)

I'm not a huge Metallica fan, but I may check out GH:M at some point (when it goes bargain-bin, for example). The very NOTION of Expert+ is enough to send me screaming in terror. @_@;;
