Comic book movies have had an amazing renaissance over the last few years, made possible mostly by the sudden realization that you don’t have to butcher the source material in order to appeal to a large amount of people. Comics always had detailed plots and characterization, but before recently the second studios heard ‘comic book’ they started figuring out ways to make the movie resemble the books as little as possible.
The same cannot be said about video games.
Whereas movies like Iron Man and Nolan’s Batman series made bucketloads of money while not compromising on the quality of the comics, it proved to dollar addicted studio heads that you can make a successful series without pissing off every single fan of the property. This hasn’t happened for video games yet, in fact the exact opposite has happened.
