Why is race and nationality ignored so much in the lore? (why does the lore fail)

[Abriael]

Marketing does not teach that. It teaches different people have different values and react to different things.
All human brains have a number of "core" features, such as a drive to reproduce, instinctual reflexs, etc. These are all products of evolution over millions of years.

And still even those features vary from person to person, in intensity, detail, orientation and so forth. But do go on oversimplifying

If there weren't "average people" then everyone would be completely unique and nothing would appeal to a large enough group of people in order to warrant mass production.

Put another way: If there wasn't an ingrained genetic reason as to why humans enjoy games, and only a few people liked games and they all liked completely different types of games, this MMO would not exist.

Do they teach to resort to meaningless strawman arguments in behavioural sciences classes?

Marketing teaches that there are many "averages", and that new "averages" can be created every day, that's the whole meaning of target. Cereating any kind of product for some abstract kind of all-encompassing "average" (including games), is something that can lead only to failure.

Walls of texts in video games and movies can be done but why do that when it's the wrong medium? Go write a novel if you want to write one.

And says who that it's the wrong medium? Videogames were born with text, even MMORPGs. Text in videogames will never go away, as it's a foundational part of the medium.

People don't understand the medium they are using if they make a video game with ten times as much text as there is interactivity.

I'm quite sure that "people" from Bethesda, CDProjekt, Bioware and, mind you, even Square Enix, understand the videogame medium quite a lot better than you.
