Not trying to be rude, but Japanese games do appeal to people with more a neurotic, OCD brain. Their entire culture is basically steeped in OCD mechanics and their video games are no different. I can see why you prefer their games. 

I fully agree. I've always felt a sense of affinity with Japanese culture.
That said, I'm also very sensitive to visual beauty, and I think Japan also wins here, hands down. Not talking about anime (though I don't mind it), but the imagination displayed by their top studios is unparalleled.
I think MGS is actually the perfect example. Look at how bland and boring Splinter Cell -- the most similar western series -- appears by comparison. And then, take any other series which uses a modern day / slightly-futuristic sci-fi setting, like various entries in CoD or Battlefield... or countless other series. They all fall flat by comparison.
I'm only saying, plenty of Japanese studios display this kind of visual imagination. Platinum games, FROM software, Capcom, Grasshopper Manufacture, SCE Japan, etc.

Now how about "Lords of the Fallen", a Western knockoff:
