I have no interest in engaging with this fallacy, which is a very common defense of bad games (not that this one is), policies, and mechanics (it's these latter two): that 'success makes everything OK.' Firan was a very successful game, but also featured some of the most horrifying staff policies and culture in the history of the hobby, and one can imagine it would have been a better game if it did all the things it did well while also not being run by an incestuous staff clique full of high school mean girl personalities and a couple borderline sexual predators.
Saying 'it did well!' does not justify bad choices along the way. A game doing well while having FCs does not make FCs a good idea. Etc.
