The game is 'GOOD' but to make it 'GREAT' you desperately need to add in more intimate scenes. Without those intimate scenes, the game becomes a failure. I don't wish to see that happen because the storyline is great.
On the contrary, more sexual content wouldn't really fit with the story, you play as a 'hero', not as a sociopathic wannabe ladykiller. You want to help them because thats what you, as the mc thinks is right, not to make waifus.
