Good girl gone bad has no grind whatsoever. It's entirely 2d. The point is story. I will say this with the trainer games, training is in and of itself a grind. That said, I haven't played them so I can't speak to their quality.I understand you're talking only about DAZ3D (you can create a lot of images).
For an example: Trainer Witch by Akabur (it have grind and a litlle images but this is good game).
