i mean a game with a plot, like cheating, consequences, girls with different personalities. To effect of comparison Defending Lydia Collier is a excelent one.
Point is... this game has barely any plot.
It is just a "daddy fucks them all" game. It just feels better than all others because of writing and girls with personality.
But plot? Objectively? There is none.
You could also play Pale Carnations. Extremely different setting, but a lot of different personalities and the potentiality of cheating.
Summer Heat also looks like it will have consequences if you whore around, but too soon to tell. I totally enjoyed it.
Personally, I strongly recommend Acting Lessons, and it is finished.
These are all games in which, ultimately, what matters are relationships with the character. Pale Carnations setting is way more complex, but I recommend it as I have a feeling you are looking for sex heavy games. Summer Heat does not have much sex yet but seems heavy on cheating consequences.
If you dont mind the total lack of sex (at the moment) I strongly recommend Summer's Gone.
