I've had my game for over a year now, and I still can't crack the top 50. It was at a fairly busy local arcade for about 10 years, so it's seen a lot of play.
How do you have your controls set? Standard or inverted? I set mine to inverted. Overall, I like it better that way- but it makes the Boba Fett/Darth Vader fights kind of a pain in the ass (the diagonal commands, in particular, always mess me up).
I've beaten Boba Fett and Vader individually, but I've yet to beat them both in the same game.
What was your score? I honestly don't know what my HS is, but the highest ranking I've received is General.
