A thought is moving (and updating) the images slideshow under the Featured Media header, next to the video shown.
In addition to this what about placing the affiliates section within a box that does not have a white background, so as to make the other wiki's images easier to distinguish? And what of the other Tom Clancy [game] related wikis; perhaps their images could/ should be added to the section. Being able to click on the images and have them linked to the actual wiki home pages would also be useful.
Beyond that how about a section on the home page linking to Ghost Recon community/ fan sites?
