Well true enough regarding the content of the game, I was referring to when Joe joined the team, and development actually increased in speed for around the last years time(which was also when their revenue starting increasing). They have put "some" lewd stuff into the game, but its mostly in the teasing areas except for those scenes you already mentioned - so yeah, very little real erotic content compared to how many years the game have on its back.
I think most people support and like this game for the very high quality artwork, and perhaps also some for the mechanics and / functions within the engine itself.
And perhaps mostly because "what it maybe can turn into" in some distant future in many years
- A really high quality porn game.
