i know you're a nintendo fan so i'll try to put things in terms you may appreciate.

demon's/dark souls or bloodborne is mysterious like how super metroid was mysterious.  there is a deep engaging story built into these game but you can also simply ignore it if you don't care.  it's more of a show instead of tell method of story telling.  it's subtle at times but also rewarding and intriguing.  also a big part of these game's gameplay is exploration and discovery.   if you just came out and said everything about everything you lose that joy of discovery when you put the peices of the puzzle together.

demon's/dark souls or bloodborne is difficult like how donkey kong country (or some mario 3 levels like the air ships) was difficult.  that is to say they aren't hard but their is a rhythm to the gameplay you need to learn to succeed.  each enemy has a very, very scripted AI.  it does the exact same thing every single time you play.  the hard part is learning what enemy's to kite, which to rush, which to parry, which way to dodge, and the timing of when they are vulnerable.  it's no different than DKC where there is a jump that comes quickly and requires precision timing land.  the first time it is "cheap" and the second time it is "easy".  again, this feeds into the joy of discovery which is so fundamental to gameplay.

it's unforgiving of mistakes but not cheap.   like games of yore you will die,. a lot.  but if you have even an oodle of patience you'll learn from your mistakes.  ..and the feeling of accomplishment when you succeed is immensely rewarding.  compare that to the majory of games today where death is an impossiblity or minimual setback to a checkpoint that occurs every 2 minutes of gamplay you'll find that these games are novel in today's market.
