I affectionately call both Revenge from Mars and star wars episode 1 "The Prams".
You could fit 4 x wheels to each machine and push it down the street and it will look just like a babys pram.
It was a huge jump in looks for anyone who was pinball educated, looked very much like a colourful mutant midget design, but definately gets people saying "what the hell is that thing" ? They grow on you after a while. The video stuff on both models is definately entertaining at the expense of serious game play/ball placement shots etc.
Has time been kind to the Revenge from Mars/Star wars Ep 1 models, or has it been unkind, is the question ?
