My DS was a Game Design major at GMU. He had paid summer internships (lined up by GMU) each summer. He was hired by a top gaming company before graduation and is now hired by Microsoft. All of his work is computer driven. Computer Science has more math in the coursework. Anything Computer-related is very hot at GMU and in demand. FWIW, the hot hot hot major at GMU right now is Cybersecurity. Those kids are deluged with offers before they even graduate.
When you tour be sure to visit the Prince William campus - which has state-of-the-art tech equipment. Many of my DS classes were there (you take a jitney bus) as is the Virginia Game Design Institute. Also, ask about the Mason Korea programs. Many of the computer students, and especially the cyber tech ones - love spending time there.
