Late last week I finally got to bring home the Met Premium I agreed to buy, sight unseen (just in pictures) and having never played metallica at all, about a month ago. It plays well (as I'd expect from a 2017 game) but definitely needs a good cleaning. The ColorDMD and HIRES combo on this thing is gorgeous, and I really like the powered blades it has on the sides. It gives a great effect when the game turns off the white GI.
Aside from general cleaning I seem to have the same issue a lot of prem/LE owners have: a chattery snake and the occasional "can't close" error message.. but it seems to work fine during gameplay, or at least I think so... I did have to adjust a few other weird things (behind the opto for sparky it was getting light bleed because the paper was folded the wrong way) and the cliffy in front of the jaw is.. not even secured on one side. I was thinking about just 'downgrading' to the captive ball setup on the pro because I think the block looks dumb anyway.
Hopefully I can get the snake to be a bit less......annoying. I think that's the only gripe its really giving me thus far. Awesome game -- of course being a lifetime metallica fan helps!
