Maybe a less intense example here is, for example, custom shaders. You can get better terrain systems that do exactly what you want, etc from the Unity asset store. Especially for a software engineer, there's of course always the fantasy of coding everything on your own. I might not get a platformer system because that seems "fun" to implement, but shaders often feel so beyond me that I'd just rather get someone's optimized shader.
