Quoted from gdonovan:. The vast majority of people I have over the house that are "pinball newbies" have the impression that pinball is nothing more than randomly hitting targets and things just happen.
Agreed. People think it's just slapping flippers. My buddy loves pinball now that I've explained there are goals and rules and targets and how to score. Blew his mind.
Surprised nobody said Star Trek (stern). I owned it for a while and loved it. Great example of easy to play, deep enough to keep you coming back, but simple enough to walk up to and jam on.
