I think there's an argument to be made that people who typically buy comics would be more inclined to respond to the coverage created by video games than by movies and, as a corollary, the people who are into video games are more likely to pick up a comic book tied into the game than people who go to movies are.
I would agree with the second part of your statement but not the first. Comic fans would be just as happy for the big screen adaptation of their favorite characters as they would be to play the characters in a video game.
