Theme integration, great ruleset, and sustainable multiballs are what make this open-layout, wide-body so addictive. Fairly open, symmetrical layout is very approachable for beginners -- and the depth of the ruleset/modes help prevent this machine from feeling too repetitive.
I had the opportunity to play this game for some time on free play -- and I can't imagine ever dropping quarters into this pin at another location. No matter how much time I spent trying to like this game, it just wasn't enjoyable. Sadly, the hyperspace / asteroid field mini [video] games were the highlights of this pin for me. A good theme wasted on an uninspired playfield layout.
After owning this game for several years I still find enough depth in the many game modes to shoot it regularly. Hitting the scoops in this pin can be a challenge (greatly varying from machine to machine), but it's always a blast to play!
