Netrunner came out 3 years after Magic.

I didn't say that it predated magic, I said that it came about before the idea of turning cards sideways (as "tapping", "kneeling", "exhausting", "rotating") became an entrenched mechanic.

It really didn't.

M:TG and Netrunner were both designed by Richard Garfield and Netrunner's design was directly influenced by his experience with M:TG.

Cards in Netrunner aren't tapped because actions in Netrunner are limited by a player's "clicks", not just their available resources.

It was a design decision.
