No. Demon's Souls and Dark Souls is nothing like this. Those games are hard, but fair. With the exception of Dark Souls 2, when you die, it's your fault for getting greedy or overzealous. There aren't any "bull****" deaths in Dark Souls.
Level 9 CPUs in Smash Wii U are literally designed to be absolutely unbeatable: they perfect guard everything, they dodge religiously, they punish, they gang up on the player even if Free-for-Alls, and if your enemy has a Counter, LOL **** you you're dead.
9.0 Classic is like Dark Souls if the game started you in a room full of Black Knights, and if you beat them, you have to fight Ornstein, Sif, Gwyn, Asylum Demon, and then run though Blighttown one right after another as a Deprived on one life. And there's no reward except an achievement.
