I feel exactly the same. I don't think the problems you solve in factorio are that complex, they are just tedious. It feels like calculations that a calculator can do. It is utterly boring to me personally, I can simply write a program or come up with a formula once I know what I need to make to calculate how much of everything I need. I also like to play simpler games which stimulates more of a lower part of my brain (motor control shit that feels good) no need to think too much in these game since I do a lot of that in my real life job. I have mostly been working on research problems where you can't generally write these rules for how to solve a particular subproblem and that feels like actual problem solving I just don't get when people say they love the problem solving aspect of the game. I mean if you think solving simple mathematical optimization problems that already have a solution "problem solving" then good for you. The average game time is too long and it is just not worth my time.
I think a lot about this in the context of video game minmaxers/netdeckers who just copy a researched, optimal behaviour. It's completely alien to me but some people really get a kick out of just being an implementer, following rote instructions exactly to the letter.
It can be but my point is when you face those types of challenges in you work and solve them you realize how much better and satisfying those challenges are in real life compared to Factorio which takes away the fun part of playing it.
