They're all great, but you've got to see Midnight Madness:
The movie is firmly planted forever in 1979, when it was filmed during the summer. If the disco music didn't do it, then the arcade scene certainly would have. It's a perfect time capsule of that era - a pinball arcade that's gradually being invaded by video games. There's a wealth of vintage pre-80's video games and pinball machines to be found here, if you look closely. In addition to Star Fire, which is the key to unlocking one of the final clues and probably the newest game in there, you'll spot long-lost relics like Indy 800, Fonz, Speed Freak and a even a few projection-based games.
Be sure to follow the links in the review; they all go to hilariously captioned screenshots from various scenes.
And this will probably be the last journal entry from me until September, as I've finished up my tenure as technology editor for June, and I'm off for Summer vacation.
So long, and thanks for all the fish. 
Aqualad. Hee.
