http://www.history.ubc.ca/documents/faculty/booker/byte-sized_middle_ages.pdfThis article seems to have some traction judging by the number of links I've found to it.
Unfortunately I can't see a good reason why other than the author's credentials and a provocative claim used to frame the narrative. The story told itself is pretty good for footnote-raiding; wrong in a few details (and glaringly missing reference to Braunstein); overall not much you couldn't find on few gamer web pages and blogs.
Nitpicking aside, what strikes me is the thesis that:
1. Tolkien begat D&D which begat Adventure which begat modern 3D-graphics-style video games, which then served as the inspiration for the look & action-style of the LotR movies
2. Kids these days think that the Middle Ages were like Tolkien, therefore like a video game (apparently of the fight-cutscene-fight variety), and also devoid of religion.
The first part of the thesis seems to ignore the fact that everything looks like a video game these days, and it has nothing to do with fantasy. Not to mention that the evolutionary link between RPGs and fighter/shooter video games isn't so obvious.
The second part may or may not be true, I don't know, but very little evidence is, er, evident in the article.
