I'm confused. You think that a comic strip that's been popular since the '60s owes it to a handful of video games made in the mid-'80s?
And it was more than a handful of games. Spy vs Spy was a strong merchandise running over many years with an unique and innovative gameplay then for many platforms.
That describes almost any comic that has been going for over 20 years. That doesn't make it bad, just played out. That it lasted decades at all indicates something good about it.
