Gbraga´s number are bogus.
TW 3 GOTY, a 100-hour campaign to many, has a completion rate of 29,3%. TW 3 vanilla is 29,7%. Persona 5 Vanilla has a completion rate of 33,5% to give another 100-hour example. Nier Automata has a completion rate of 25,7% BUT ending C that comes right before has 34,6% with it´s counterpart having 29,7%. Some gamer likely assumed that they saw the ending with one of them, which I get. Source: My current PS profile from my PS4 Pro
That said. The usual Souls is a Rite of Passage TM nonsense this de-evolved into is and always has been a load of wank. The difficulty
never made any of these games good. Reducing them to how hard they are and how finishing them made you a True Gamer TM is one of the biggest disservices you could give to the From teams.
These aren´t even the hardest genre in gaming.
PS: NG 1 and 2 on the Vita have abysmal completion rates but that´s what PS+ and years or rampant Vita piracy will do to you.
