Although I am sure that contemporary game makers use analytics to understand user behaviour and optimize for in game spending and engagement, at least in the bigger games probably the core experience comes from creative human processes.
The more the analytics the further optimised the game would be towards KPI.
Also, I suspect that Netflix is creating it's materials based on analytics rather than creative human input.
Maybe the problem is not analytics but greed and ill chosen KPI? Pre-total-tracking world, creatives still needed to test ideas and to test ideas you need to be able to measure. They would pay attention to what sells, how people react to a specific line etc.
Maybe it was more fun because it was less optimised for profit?
