Sounds like they are trying to make the argument that Scifi is more realistic than Fantasy, then claiming Western games have more Scifi elements than Japanese games. And on top of that arguing the realism makes game better.
So which one of those arguments do you want me to tear apart?
What if an RPG began when a terrorist attack took out two identical buildings in the largest city, and a President, son of a former one, used the incident to promote terror to control the people, increasing military action to obtain more of a resource that produces a great amount of energy, but which constant use is causing environmental concerns that may destroy the world. Wait no, that plot has been done, its FFVII. You know, a fantasy game.
I'm sure a plot surrounded by FTL drive or radiation transforming people into monsters is much more realistic. And let's ignore every Japanese game surrounding those elements, like Star Ocean or Xenosaga. And ignore every western game with fantasy elements like Dragon Age and Morrowind, in order to support the theory that there is an unbalance. Otherwise, the argument would be about one culture's fantasy being less realistic than another's, and that would just be obvious prejudice over different people's beliefs.
As for reality trumping fantasy, perhaps, but if you really think that what the hell are you wasting your time playing a video game to immerse yourself into someone's fictional story? Go make yourself a sandwich, that's a lot more realist. You want to level up, study a real subject or workout. If reality is better than what's the point of Role Playing?
