Most engineering is this way. Somebody needs to build a thing that isn't too different from other things on a budget and a timeline. Your typical civil engineer isn't designing a new burj khalifa. Most software engineering is about organizing a group of people to build a thing for a customer that isn't too different from other things, on time and on budget. There just simply aren't as many jobs working on wild stuff nobody has ever done before.
RollerCoaster Tycoon is, in my opinion, a great example of something that isn't really engineering. One person did it and the decision to write it all in assembly is almost anti-engineering. It is an impressive feat, but not really comparable.
