Well, I generally meant that, while hip hop has taken our generation backwards, it's influence is not debatable. It still had it's detractors and critiques at one point in time - particularly when people were more scared of it; some felt that hip hop was a trend, just a small fad that would eventually disappear. Whether video games are able to pull itself out of that situation and hold some cultural significance that can influence others like movies and music (namely rock) is questionable, but it's still a possibility.
I think that hip hop has basically failed that proposition as of now, as it has alienated it's original target audience rather than growing up with them. Video games could suffer a similar fate, but as it stands now, I doubt it.
