I do find years in enterprise made me uniquely prepared for organising my game code. I definitely see the spaghetti in there, but it's at least neatly contained in the bowls I've set out.

But it's definitely the hardest software domain I have ever tackled, and if only it were just software! Game dev is realy 6 other disciplines in a trenchcoat. Which disciplines they are depends on your game and whether or not you have help.
