Quoted from Daditude:AFM-nice game with lots of nostalgia. Good theme and fun callouts. Very good light show, and it rakes on route. Repetitive gameplay...once again..with rules that don't equal newer games.
Metallica-arguably the best rock pin ever. The music is great, the toys and lights how are incredible. Flow is amazing and it has that one more game appeal. There are a lot of rock pins, so it can get muddled in them. The art is not for some. Not really kid friendly.
For me, this is the matchup. AFM and MET are two of my favorite games, both fantastic in their own right.
