It's been a long time since I kept current on games.

Reading these descriptions, I have only one comment:

What the *HELL*?!!?!!!

Don't knock it until you try it. 3 of the 4 games are highly rated, winning multiple awards. One frequently is mentioned on HN as one of the best games ever.

Games are a medium to tell stories. If you can conceive a TV show or movie tackling these themes there's no reason to think games should be exempt. In fact they are far superior in addressing these themes than movies are.
