Con Pause feature
Europa Universalis IV features a pause feature to let players think over their actions indefinitely while looking around the map, meaning that users can read manuals, guides and look around the map thinking of what to do next even during online play, resulting in a less complex game
Con User friendly interface
Europa Universalis IV features an interface designed to be understood by a user without any prior knowledge using tooltips and icons to explain what each button does. While normally this would be a good thing, it's certainly not what you want if you're looking for an ultra-complicated game.
