Which areas of game development are worth handing over to someone else?
I've always been a learner of everything—3D, audio, programming, etc.—and the consequence is that I'm not an expert in anything, but I'm now reaching certain areas where it's required to specialize for years, in my case, I underestimated animation too much.
But this post isn't about me; it's about those specializations that are better left to someone else, and there must be a few beyond animation.
What would those be for you? Texturing? VFX? Dynamic Audio? Modifying the engine?
Note: only those skills that are truly worth giving to someone else, not those you can learn in a few months and achieve decent results with.
