I loved the 2 games, more the first than the second. I didn't know anything about the universe of The Darkness, but I was blown away by it.
Never mind the story, guns, powers, acting, load screen stories, the drab yet living subway and its npcs etc, it was the first game to make me say "aww, that's nice" in regards to certain optional action watching TV, and to actually feel so angry and vengeful the way the story went shortly after that. Dunno why I got so invested so quick, but I wasn't complaining.
As a PC gamer full time now (for the past few years) I would love the first to be on there as I think only the 2nd game is. A third game would be welcome too of course.
