Ghostbusters - Awesome theme but cheap feeling game. I swear at least one out of three balls is lost by it jumping over the flippers. I'm bad enough at the game without feeling cheated on top of it!
Orbitor 1 - snoozefest!
F14 Tomcat - just cant get into this one
Honorable mention: Judge Dredd, Mr & Mrs Pacman, Metallica and Stern Star Wars.
