I initially found Factorio interesting, mostly for the parts that encourage spreadsheet calculation, e.g. balancing the various rates of production and resource intake. Some other aspects appealed too, such as finding drill placements to fully cover ore deposits.
Where I lost interest is when the game became mostly about refactoring large transport belt networks. That reminds me of the non-fun aspects of programming.
(That, and building vast quantities of artillery in the middle of almost fully red zones, then flipping the power switch for the loaders and watching the fun. :D)
