Well there's always the God of War III remaster. I tried that game on the PS3 on the hardest difficulty, and couldn't make it past the first "real" boss fight after the tutorial boss, Poseidon. So if banging your head against a brick wall is your forte, there's that.
With the Souls there's also the Dark Souls II remaster, Scholar of the First Sin. It's the same game, but you can join the Covenant of Champions immediately upon arriving in the hub town, which increases the aggression of enemies, makes you take double damage, and has them respawn infinitely. For even greater masochists you can take the Bonfire Ascetic as the starting gift and bump Heide's Tower of Flame into new game+ straight away, which makes it an absolute ***** of an area.
