The most generally useful degree would probably be any CS degree. For whatever you do though, your degree will only be what you make of it. If you want to do game dev, use the resources you have in school to actually make stuff. You won’t have those resources again for a long time. The internet can be great, but having someone who can look over your shoulder and show you exactly what to do or draw diagrams for you or whatever. You also get access to tons of cheap software and tons of professional development opportunities and ****.
Personally I’d go with a CS degree just because of the whole “a programmer can make an ugly game, but an artist can only make a pretty picture” thing. Really at the end of the day as long as you’re actually doing stuff anything is fine.
