An hour into my time with Heralds of Chaos, I found myself wondering why it's so hard to find something like this among all the other social trading card games on Facebook. Its gameplay may reveal a greater focus on polish than innovation, but I've nevertheless experienced few other social trading card games that do such a good job at hammering out an entertaining narrative from a game about cards. Other card games have seasoned their gameplay with stories, of course, but Heralds of Chaos does it so well that it's enough to trump some of its shortcomings.
