What was the most expensive state of the art arcade game your arcade had?

For me it was Sky Pirates.

It was a VR game where you sat down in a seat that goes up and down as you follow your hot air ballon. you had to battle other players hot air ballons and you had a drop attack where you popped someones ballon from above
