It will be kinda obvious but look out for wear around the flipper buttons if it doesn't have the lollipop rails .
Check for a broken funnel at the entrance to The Ring ( easily replaced but a bonus if intact ) .
Check for a broken / damaged "Arwen" plastic . It's the plastic below the exit of the Path of the Dead mini playfield on the left . It normally has a picture of Liv Tyler's face on it . ( Again , easily replaced , and there are options for protectors to install to prevent further damage ) .
Apart from that check for playfield wear etc.
Great game . One of Sterns best , if not the best .
