I've had my fair share of porn games, some with really funny writing (Akabur games are always a joy to read through), one, in particular, was even debating taboos and society (vitamin plus).
But LomL particularly does something that would be unthinkable for a porn game, porn isn't the focus of LomL. The two main characters, Denise and Macy are not there to service the player, it's quite the opposite, we are there in service of them. The MC relationship with them is much more fatherly than romantic, they just went through the shock of losing the most important person of their lives, and we as the MC/father are there to reach out of this rock bottom situation.
The game makes us care first about the characters first then add the porn later, and honestly, I have never seen this done before. Even mechanically the game enforces this idea, as the main characters struggle with their major weakness (anxiety and rage), or how the MC is still coping with his loss when he is alone.
LomL is the kind of game that I care more about choosing the option that will make the daughters most happy than if It will result in a sex scene.
