GB: "When people think of world domination strategy titles, their answer says a lot about who they are. If they say Risk, you can guess they're old and not particularly tech savvy. If they say Civilization, then they're probably a tad younger and into PC gaming. If someone answers with Europa Universalis, you should stop what you're doing and shake their hand. Europa Universalis IV is the big boys RTS, but it's an exercise in tactical depth and design frustration in equal measure."
