The problem is that for DAZ art specifically, there are only two goblin models with modern enough detailed textures. On top of that, for one of them, no penis model fits it properly (it attaches to the stomach). Unless someone is very proficient with DAZ and the models involved, they won't be fixing that issue. Then, neither of the two models is easily morphable as most morphs aren't designed for these goblin models. That's why we usually end up seeing this one as the penis models actually work for it and actually looks good like a goblin. Far better than the ones who try to morph a normal human model into something resembling a goblin and changing the skin color, which just looks comically bad.
Maybe this kind of game just isn't for you. The monster fetish is usually an ugly monster with beautiful women and that's what these games try to play into. So I don't think it's about laziness, it's more to do with the established fetishes and the difficulty of actually doing otherwise with the available monster models.
