It wasn't necessarily difficulty that ran me off. I'm not one to necessarily need a hard game. Although I would say their difficulty curve was usually sort of challenging at the beginning until you're about 20% in and have learned the gameplay and have some upgrades. At which point it's totally trivial.

They just lost their variety to me. All third person action/adventure with mildly different ways of attacking like some being more ranged and others melee. Typically always a stealth section or two. I've played all the old God of War games at least twice each I think, have no interest in replaying the new one and it was my favorite exclusive game on the machine.
