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.
