Rarest game you've ever played/seen/owned?

[CliveP]

I owned a Williams Zodiac , my mate has a Williams Defender ( 1 of 2 in NZ) I missed out on a Gottlieb Gemini ( the guy who got it rethemed it!!) NZ got quite a few Sega EM pinballs which may or may not be classed as rare - playfields are always in great condition and most are multiball and have some quirky feature.
