I remember DREAM MACHINE in Worcester, MA too. There's one in the Greendale Mall (sucks), and before that there was the other Dream Machine in the Worcester Center Galleria up until about '88 or '89. That's where I'd play Crossbow, Choplifter, and Xenophobe until my luck ran out.
The other (and better) arcade was the Playoff Arcade, where I'd hit Xenophobe, NARC, Cabal, and too many others to name until I moved out
of Wormtown altogether in '97.
Those days are gone, but now I've got my 7800, Infogrames Atari Collection (PSX), Stella 2600, Jum52, and Handy emulators for the Mac to bring most of it all back at my fingertips. Nothing made me feel more wisened than showing my roommate's nine year old kid Tempest, Battlezone, and Pong (!), and seeing him getting into it and giving me a run for my money
Yes, my generation will have our turn to gloat during the 80s retro craze, and after we're gone, these games will always be a part of the culture, and they'll never die.
