I'm lucky enough to have one of these. Todd's video is really good, I have watched it a few times to help understand the game.

I have had the trio - BH, HH and Spirit. HH was sold a while back, and I still love my BH. Spirit is very much in the "great" game category for me.

There are a few things  that make it a choice game.

Great sounds - no voice, but a nicely implemented set of sounds and effects that suits the theme really well.

Fantastic shot map - including a great shot to the upper left that is hard but extremely satisfying to make. Has to be one of the longest shots in pinball.

Terrific artwork - unusual and while there is a lot of black on the playfield, it doesn't seem dark.

Good rules, and a very hard to achieve three ball multiball - it's always available (to lock the three balls including that long shot I mentioned), but each 10 point switch changes the available ball lock between the three (then between the remaining two when one locked), making it really hard and you need to plan shots carefully.

Great 2-ball multiball is also available from the "Stargate" - this is easier to get (but still hard!!) and is accompanied by a different sound track which I really like.

The outlanes have the little "saver" flippers, which make up for the massive distance between the main flippers, which is at least a centimeter (maybe more) wider than most games.

Overall a very challenging and rewarding game. Up there with the best of the early 1980 games IMO.
