In a nutshell, no. What you are seeing is more like this:
The game system is easy. But there have been several variations of it over the years. Each with its own supporters. So what you are seeing are people going over the high end details and what they think is better or worse, or just what they would prefer.
Think of a game engine as a car. Learning to drive isn't too tough. Deciding what sort of car, what color, tires, radio, the horsepower of the engine, if it should have bullet proof glass and armor. All that has little do do with actually driving the car, but could have a lot to do with getting the car to do what you want it to do. Since we have a hundred people here who all want to use the same "engine" to do something a little different we get disagreements.
Since we all spend time on and care about our gaming experiences, we can take it all a little too seriously, putting more effort into minutiae than needed, and making little differences look like major ideological differences.
But it is really choices rather than difficulty.
In the end there are only two things to remember.
