Oh, the overal narrative was the same, but several details were changed. I liked how they previously had to prepare to face the orcs. Now they just have to fill up a bowl. And I disliked the change from werewolf to wolfpeople. Werewolfs are cool, wolfpeople ... not.
There was only one part I had to "grind" and that was one of those additional last quests in hell where locked and drain enemys appear. All other stuff was done at the second try at most. Some button mashing and releasing the combo energy. I finished in 28 ingame days, girls ranging from lvl 30 to 16. And I did not even do brothel work every day.
Since you cannot level up the girls manually, you just switch when energy is low and mash the button, there is no strategy in maximizing any stats. I guess that is why the game now has "action" rpg as a tag. The way the combat mechanic is , with the meter going up and down, it is vulnerable to just pressing the button really fast, so it does not go down often enough.
