Williams Liberty Bell - Pretty nice looking (not it's strong(est) point), but fantastic rules, play, reliability, and GREAT speed with those factory-DC pop bumpers and flippers. Nobody has really caught onto this game. This game will not be leaving the basement and will share the basement among some of the best of the best. I thoroughly enjoy this game, and you will have to squeeze every vantage point you can get out of it as you work on upping your rewards. And that's only playing alone! It is two player and makes for a GREAT friendly-competition game and know that from experience. Picked it up really cheap in GREAT shape and I expect you'd easily be able to do the same. Rips a unit that controls two lighting effects in sync, off of the spinners, which produces a cool light show and an orgasmic EM sound when you hit them hard.
All in all a really fun skill-based game that is very easy to learn and very difficult to master. Extra Balls, bonuses, SPECIALs, and all that great stuff as good rewards to expand your game and score. Love it!
