It'd be nice to get my BA in History and be done with it, but seeing as how that's not very useful, I unfortunately have to go all the way (or at least with a Master's) to be a college instructor.
But hey, I like teaching, and history was always an interesting subject, so I don't mind too much. The other reason is that I've heard most game designers are had degrees in history, which sorta makes sense since it would be useful to know some shit that you could tie in with the games you're working on. Yeah, yeah, the odds of getting such a job are pretty rare, but that's why I have a backup plan.
