though with a computer game you can be confident that there is a
solution, while in real life you may find that you need to move the
goal-posts, or adjust the client's ambitions.

 
Trying lots of arguably crazy ideas is educational, and has a chance
of stumbling onto something really valuable. But one has to do it
fast, because there's literally a universe of possibilities to
explore.
 
Exploring Colossal Cave is a good analogy to exploring the electronic
circuit solution space, except the circuit space is much bigger hence
impossible to explore serially.

Most circuit problems have a single input and single output, but the
space in between can be as complicated as you like.

The set of all circuits that can be designed from the Digikey catalog
is past 2-dimensional.

The trick is to use a good search algorithm.

If the problem you are trying to solve has conventional solutions, these
can serve as known routes through the territory you need to explore, and
I've had people reject my short-cuts because they didn't understand the
problem clearly enough.

Yes, most people reject unusual solutions for several reasons, one
being jealousy that they couldn't think of it.

Conventional solutions will have lots of competitors, who have to
fight it out by under-bidding one another.
