Another few things to consider
Many students change majors. Which school provides better options for your student if they don’t stay in game design? Would they go to a different CS discipline? CE and hardware? Other Engineering ? Math? Physics? What about dual majors?!
WPIs curriculum is very flexible but also has the strange short terms. Which one is a plus?? Or a minus??
Both schools seem to climb people’s list when they visit - no surprise there. But what about more mundane things that matter to success at college like: distance from home, tutoring, and life/mental health support.
