Is your avatar your horse? It's nice looking.
But anyway, to the topic at hand, I do love stories with good action and lots of adventure. I love when the characters get in trouble and I have absolutely no idea how they're going to get out alive.
Post apocalyptic is cool. I'm not sure about zombies, but something slightly realistic would be good (integrated circuits quit working, economic collapse). Exploring new territories also sounds like fun. Maybe we're accompanying a cartographer?
