Except the first two months in game where i need to develop my fitness skill, fighting, massage which take about 15-20 min to do so, i don't see any grinding at all. I don't like cheats, feel like missing a hole story and i like a bit of a challenge, but if you play in an organized manner ( not going after all girls in the same time just 3-4) you'll have action in no time and won't miss a thing. If is only for fapping just look in the folders, like the previous post says, but Avenger makes good stories and is too bad to miss them.
