Quoted from LesManley:Total agree they are different...but they are supposed to be the same game and I feel the differences on the Pro, compared to the features on the Premium / LE are large and change the game completely...just like you said.
Only he didn't say it changes the game completely. He said they 'play differently'.
Of all the games with pro models, AC/DC is by far the best pro. I'd rather play an AC/DC pro than any other LE or pro (other than an AC/DC premium/LE). The compensation for the missing hardware is perfect. The scoring is lower than the LE or premiums, but the play is faster. Not having that annoying swinging bell block the bell shot is worth the price of admission alone. Way more fun than either version of Tron. Tron's not a bad game mind you. Just not in the same class as AC/DC.
