As someone who'd never seen either movie, I thought BSD and Tommy did a pretty good job of giving me an (incorrect, it turns out) feel for what the story was.

One time I pictured a game in a generic fantasy setting where the whole playfield (flippers to shots) was a big map with lights under each location, and you could navigate across the map, going to different cities, etc through your shots. Part way though you could get ambushed by bandits, etc.

Often my friends and I mix it up by playing games just for number of modes (either completed or started, depending on the game, but you're not allowed to time them out). Seems to work just fine. Score is the tie breaker.

And there's a reason new types developed as well. People like different things, amazing.
