Historically, middle-of-the-season DLC in Anno games tends to be weaker than what you'd get at the start or end. It's something for later expansions to build on, not necessarily an exciting addition in itself. So I had measured expectations for Anno 117: Pax Romana's Hippodrome DLC, and that was shortsighted of me. Sure, it's just one monument-class building. But this thing's great.
