Factorio does a great job of modelling some failure modes of scaling systems.

For example, your train bus smelting depot is fantastic until you suddenly realise you have train throughput issues and need to completely rethink your rail architecture to keep up.

A word of caution, it's called 'cracktorio' for a reason: it scratches a certain kind of itch in a certain kind of brain troublingly well.
