Ha! I was going to say the same game! HH was a wonder to me when it was unboxed in my local arcade. It was amazing, what a game. But over the weeks that followed, it seemed to be down quite a bit. Then it would be running and I would have a blast again. But it didn't last long. Eventually they yanked it off the floor because it took so much work to keep it running (it was a very busy machine while working).
My fond memories of the game lasted for decades, but I never ran into another copy until a few years ago. I was so excited to play a restored copy... until I played it. All of my wonderful memories of the game were shattered by the game I was playing. The game itself played great, but I had changed. I did not enjoy playing it at all.
Hercules was kind of the same for me. The arcade got it in brand new, and I played it the next day. I barely got to know it though. Because I don't recall it ever working again while I was there. I'd ask, but they would tell me it was down, and they didn't know when it would be working. About 10 years ago I ran into another one... and it was interesting, but a big old no from me.
