There are extra Bally games that are missing from this list, if you "roll the clock" back by only a few months in manufacture, not years. Many titles used the Bally AS2517-35 or Stern M-200 MPUs very effectively and to their maximum limit.
My preference is Mystic, and not for exclusively for preference of the artwork, but the gameplay and ruleset which are equally comparable. I give special note and mention to Mystic early production examples that included the 3D illusion "all seeing eye" insert and reversed cabinet colors.
People may not realize quite a few titles in the past 30+ years took inspiration from this George Christian designed game in terms of both rulesets, artwork, and gameplay style, but it is often overlooked.

Added over 6 years ago: Mystic is classified as a "1981 Bally" by pinball historians as production commenced in June 1980, and concluded in March 1981.
Its production run was not insignificant or small at 3950 units, which was HIGHER and MORE SUCCESSFUL than Fathom or Centaur.
It uses the EXACT same board and functionality of games such as Fathom, Centaur, Eight Ball Deluxe, and other mentioned titles.
