Mad Max is so good. But if I had to pick a theme, I really enjoy natural disaster apocalypses, like Day After Tomorrow. Tsunamis, earthquakes, volcanoes, heck, even comets/asteroids. There's no fighting back, just fighting to survive.
I usually go corruption. I find the romance options are too shallow. Oftentimes it's too easy going the romance route, you just pick the nice choice and it works. Though I suppose it depends on the game
Definitely want my games to have music/ambiance. Done properly it can add a lot to the experience, heighten emotional scenes, etc. But I don't like music with lyrics, something about it just distracts me
