My top ten in no order
Firepower: Classic open playfield, fast, multiball, great sounds for the era
Skateball: Nice to see this one getting love. one of the worst back glasses but everything else is spot on!
Space Shuttle: Speaks for itself
Black Hole: Lower playfield...love it
Laser Cue: Stupid theme but honestly one of the best players in the bunch. strong flippers. super fast
Meteor: The shot off the left flipper straight up into the spinner is one of my favorites to this day
Strikes and Spares: Lots of great shots, still has an EM feel but the pace is faster
Tri-Zone: Now don't laugh. at 7-9 degrees this game is super fun and fast. you should try it!
Time Machine (Zaccaria): Just an absolutely incredible machine...to play AND just to look at
Black Pyramid: again, don't laugh. it's one of those with simple shots, and couple of difficult ones. i should get bored and walk away and yet just keep playing and playing
Honorable mention:
Kings of Steel: If you like Skateball you'd like Kings of Steel as well
Flash: great one
Xenon: to look at. actually sucks to play
