lol there are games like Summer's Gone and Hillside which if I'm not mistaken have been in development for similar length of time to DeLuca (if not longer), and have no sex scenes yet (in fact, Hillside only has couple more updates to go until game's complete and there's still no sex scenes. Despite that, great game that's enjoyable).
And yes, those games devs also have the "story first" policy of the game which the dev maintains, as well as the people who complain/whine saying "where are my sex scenes!" (particularly those who want quick fap lol)
So no, I don't find that to be a valid thing to say.
Just people who whine feeling entitled, because the dev is not following their demands.
For those people, I'm actually tempted to say they should try out games like The House in Fata Morgana, a great game but has zero sex scenes
