Black Hole, was a game i just thought sucked, play wise...
Boring slow and just a let down...
I had played a few at shows, and thought OK, i'm good...
The first 2 i played were weak, and i guess you could say tired.
Then i got to play one at a show that was in pretty good working order and i though well this is a hole pile better than i remember.... Hmmmm ?
Me being a Gottlieb guy through and through it was tough for me not to like it before, i am glad i got a chance to play one that had some actual substance to it...
Fast forward to about a month ago, i went to pick up a Star Race for a guy in a trade deal, Laser Ball for star Race, and there sat a Force II, and a BH...
I loaded up the SR, and bought the Force II also, as that game NEVER comes up for sale EVER !
after all of that back breaking work, i gave this guys BH a shot, the game played pretty snappy, and i would say for the most part it was 100% working except for a sound issue...
So here i am, a full truck, not enough cash on hand in my pocket anyway, and a BH that the guy said he would sell me even though he really didn't want to.. had to leave without it, but told him in 2 weeks i would be back for it...
FF again..2 weeks later its in the back of the truck heading home.. 
spent a ton of time de-cobbling things, and dialing it in, full major shopping..
What a fun and punishing game if set up right...
I thumbed my nose at it for 4 yrs, ....4yrs without a BH i can never get back LOL
Great game, and glad i gave it the chance every game should really deserve...
lesson learned !
