I am not too sure if websites are targeting Nintendo games for bad reviews Spruge-Senpai. I will say that Xenoblade Chronicles should have received a better score for many of the reasons you listed.
However Senpai, at the end of the day, it is just a number that should not dictate your opinion of the game. Keep in mind, reviews are merely opinions. Everyone will be divisive about them as there is no one right answer. They key of it all is if you are enjoying the game.
