The west praised challenge, it was all over marketing and magazines, magazines having scores dependant on a game's difficulty (difficult = good score, too easy = "this game would have scored higher if it was harder"). The older the game, the more true this is, and with each generation it became a little less true (though you can still find magazines doing that in the 5th gen, even Nintendo ones) until it started becoming untrue during the 7th gen.
People don't know this or have forgotten it because they've been used to a completely different paradigm since then. When a game was difficult, the average western player didn't mind (they didn't come crying about it), or he was glad, it was a good purchase with a good bang for its buck.
Now, while this mentality was proeminent in the western markets, it wasn't in Japan: you will not find magazines and marketing praising difficulty that easily.

According to an interview by Mikami, Resident Evil devs couldn't even beat the prototype versions of RE1 and were struggling with the controls. They made it harder anyway for the final release. And then they made it even harder for the western version.
There is an interview of the same person explaining the regional difficulty difference on rentals; and then there is another interview explaining it by what I just said (the difference of mentality between west and Japan), though admitedly I've lost the source to that one (I read so many back to back and I can't find it anymore).
