Engineers have to do work.. I would unit test core libs... I would also hire manual tester because they were very useful. I'd likely not chase down 100% automated coverage. The goal is to ship a game not have 100% coverage. And I work 100% pure tdd in my day job and side projects so take that for what it's worth.
