The thing about video games is that they’re a multivariate equation. Fun is a variable, and so is realism. Depending on how much realism there already is, and the nature of it, adding more can also increase the fun but it can also take away from the fun. There’s a reason that even the hardcore simmers who do things like drive pretend trucks across Europe in real time or run pretend air traffic control at pretend airports pay to pretend to do those things instead of getting paid to do them for real.
