Sure, and there are a lot of other things you don't /need/, but that will make you more valuable to employers, or to your customers if you're a business owner.

Everybody has to choose things to learn and not learn, but my experience has been that putting math in the "not learn" category can make your life/career more difficult in some job markets. If most game devs decide they don't need to know math, that's just more opportunity for me, so I'm not too bent out of shape about it. :)
