All the time I see people who say "The game is too easy, please make it harder." Not just for D:OS2, but in the forums of almost every CRPG.
Baldur's Gate 1 & 2 (Enhanced version added the Legacy of Bhaal difficulty) did difficulty settings the right way.
A near impossible (Legacy of Bhaal) difficulty for the 0.00001%.
An insane difficulty for those who wants to get punished for any mistake they do.
A hard difficulty for the veterans who enjoy min-maxing.
A core rules difficulty for the veterans who wants a challenge.
A normal difficulty for those who like it hard but not unforgiving.
An easy difficulty for those who just want to play the game without too much challenge.
A story mode for those who just want to play for the story without stress.
Baldur's Gate 1 & 2 difficulties:

Then you also have Pillars of Eternity which did difficulties the right way, albeit with fewer options than Baldur's Gate.
Easy for those who wants to play the game without too much challenge.
Normal for those who wants to play the game with a bit of challenge.
Hard for those who wants to play the game with a lot of challenge.
Path of the Damned for the truly insane.
Pillars of Eternity difficulties:
http://www.gamerevolution.com/images/misc/Difficulty.jpgIn Pillars of Eternity, there is even an achievement for finishing the game in Pillars of Eternity with Expert Mode (Less helping features but more notably, no telegraphs for abilities (No circle showing the range of your ability or the area of effect it has)), Trial of Iron (Only one save file that gets deleted if your character dies) and without taking any companion in your party.
And yes, some people manage to do it by min-maxing, abusing every single overpowered thing they could use, murdering as many things as they could for extra XP, gold and items as well as stacking consumables.
