“Really, since it was one of the first titles for the NES at all, Kung Fu paved the path for several ideas: The beat-’em-up genre as a whole, and the idea of porting arcade games to a home console.”
– from the full review, which you can read here.
Although that line is in the review, I should probably clarify. Somewhat obviously, arcade ports had been done for earlier systems, notably the Atari 2600. Kung Fu, more accurately, was one of the Nintendo Entertainment System’s initial thrusts into that arena. Looking at those original 18 launch titles provides an interesting commentary on Nintendo’s choices of what to develop for their brand-new home video game console, with such high hopes riding on it. I am not sure precisely how well Kung Fu delivered on those lofty expectations, but I would say it definitely played a part.
