Quoted from Rarehero:
That's some troll-ass game rating. I think Ghostbusters is a garbage fire...but my rating ended up as a 5.3 lol
Tell me about it. How in the **** is Metallica ever a 1.21? The code is complete, the rules are good and provide strategic variety, there's several good multiballs, there's no single-best scoring approach, plus it means he scored it a 1 for art on playfield/glass/cabinet and animations. Sound QUALITY is objectively good even if you dislike Metallica's library. The layout is at WORST derivative of MM / AFM. You could argue the Prem/LE features add very little above the Pro, or sometimes cause extra mechanical problems that need chasing. Total troll score.
I can't comment on AC/DC because I haven't bothered to play it (don't care for the band), but it has always looked to be at least a 7. Some cool ideas going on and fun integration with the cannon. I saw Bowen play it and the songs seem well integrated. Plus it had TONS of "firsts" for Stern that are now used all over.
I don't think even my most hated game would rank below a 3 or a 4. Your quote really is worth repeating and those ratings are on something besides what's inside the game.
