Yes, Embryon never did much for me either. OTOH, people are scooping up anything with the classic Bally logo these days.

On a side note, Embryon was the last Bally widebody, following Hotdoggin'. I guess Bally was trying to recapture the magic of Space Invaders, but no luck. By the middle of 1981, pinball was really struggling as a valid location piece and a couple of years later all of coin op was in a sharp decline.

Yes, I do prefer Embryon to Space Invaders from a game play perspective as well. The "magic" of Space Invaders was a single production run of 11,400 units. That strong run probably had everything to do with the theme and nothing to do with the size of the playfield.

With your Embryon, like anything you want to sell just be patient. Can't be that many really nice Embryons out there.
