If you like FAST, a FANTASTIC light show with AWESOME sound, BEAUTIFUL to look at and absolutely kicks you ass- you MUST play SPACE STATION by Williams. With no ball return lanes all your flipper skills WILL be tested. Get the bonus time at the end of the game for a really nice original sound track that gets the blood pumping.
As far as EM's go I really like JET SPIN, I played this recently and had an absolutely great time with this. Varitargets and rotary targets are bloody COOOL.
I am also bias towards my 2001 I am restoring as with 2" flipper and 20 drop targets it is also a great game and a classic wedge head.
