sorry, it is not because "most of the people" think that way that everyone have to think that way. Wanna speak about literature? I have few friends who actually read all of Harry Potter books and did not like it at all.
Wanna speak about video games standards? I did not like Baldrur's gate nor I liked the Elder Scrolls.
About cinema? My ex did not like the Lord of the Rings.

I agree, there are codes and techniques about "how to make a blockbuster" but they change. so if you wanna speak about what is the best option to make money yeah you're right buddy... thing is I like less and less AAA games because they are just clones, big companies not wanting to take any risks and maximize the profits.
The funny thing is that those "general rules" are slowly killing them. People want new things, this is the reason why crowfunding is working so well. As does Steam

I am not going to lecture you but what killed the US cinema in the 60's was that it remained stuck in its rules and codes.
