$25 (L)oose or (C)omplete: L

Description: A seriously psychedelic videogame record that was available through Data Age. Plugging their products with hammy actors and actresses, you might get an idea of what the games were about, but certainly not their poor quality. Classic line from this record: "The hatch key....got...to...find...the hatch key". Collector's: don't go looking in the 45 RPM section for this one - it's on a flexi-disc with cardboard backing, like the kinds you used to get in cereal boxes in the 70's.
