Johnny Mnemonic is actually my favorite movie of all time. It's based on a story by William Gibson that predates Shadowrun by 8 years.

Fallout obviously took a great deal of influence from Wasteland. I think it's much more likely that the creators were more familiar with Wasteland, as Fallout is so markedly similar, than Gamma World. Wasteland, however, was most likely influenced by Gamma World.
