TOTAN!
It has a complete story line with a beginning, middle and end, six different characters (not including monsters), a variety of settings and a ball hold magnet.

Also: Junk Yard

Another one with a story that has a beginning, middle and end, a variety of interesting characters, a “world under glass” and decisions that effect the outcome of the game.

There’s no ball hold magnet, but the bus stopper post has the same effect.

Bonus: it’s a mid-90’s era Williams at an approachable price point.
