Realistic games that goes beyond what is OK on PS?

The game Clouds and Sheep 2 (rated E for everyone), while not realistic, promotes incest.

 

In the game you have to manage a flock of sheep, so you need to force them to mate. You're given an unrelated male and female sheep in the tutorial and shown how to have them mate. From there it's all incest. Ok, ok, there is an option to buy unrelated sheep from the store to expand the gene pool, however the price quickly increases, so before long all the sheep are going to be related again.

Spec Ops: The Line is a pretty dark game and there is one scene in particular that is wicked. Anyone that has played the game knows exactly what I am talking about.
