It would be a difficult path, through civil wars, religious upheaval, great fires… and awkward unions. But the nation that would become Great Britain would rule a trade empire that spanned the globe, exporting ideals of English freedom - both of thought and trade - while making itself the most powerful nation the world had yet seen.Master wind and trade, and spark industrial revolution in Rule Britannia, a new Immersion Pack for Europa Universalis IV. Key features Rule Britannia’s features include: New British Missions: New exclusive decision trees for England, Scotland and Ireland, embedded in our new Europa Universalis IV mission system. Industrial Revolution: Highly developed provinces may produce coal in the late game, fueling higher productivity and greater wealth. Innovativeness: Earn rewards for being the first nation to unlock new knowledge, including lower power costs. Naval Doctrine: Adopt a general strategy for your fleets, giving you bonuses to ship maintenance, trade power or battle performance. Anglicanism: A new Protestant faith can appear in England with new bonuses and religious choices. Knowledge Sharing: Help your lagging allies or subjects by promoting the spread of institutions in their realms. Rule Britannia’s game improvements are packaged with New Unit Pack: New army designs for British nations, including regional Irish units and revolting nations like Northumberland or Cornwall, as well as new music. New Music: Our composers have been hard at work writing new songs to quiet the stormy seas of commerce. system requirements Windows - MinimumOS: Windows 8 / 7 / Vista / XPProcessor: Intel® Pentium® IV 2.4 GHz or AMD 3500+Memory: 4GB RAMHard Drive: 6GB free hard disk spaceGraphics: 512 MB DirectX 9.0c compatible card - NVIDIA® GeForce 8800 or ATI Radeon® X1900Sound: Direct X- compatible soundcard DirectX®: 9.0cAdditional Notes: Internet connection or LAN required for multiplayer Mac - MinimumOS: Mac OS X 10.6.8 or betterProcessor: Intel Core Duo Processor (2GHz or better)Memory: 4GB RAMHard Drive: 6GB free hard disk spaceGraphics: 1 GB - GLSL 1.3, OpenGL 2.1 compatible card - ATI Radeon HD 6750 / NVIDIA® GeForce 320 / NVIDIA® GeForce 9600 or higherAdditional Notes: Internet connection or LAN required for multiplayer Linux - MinimumOS: Ubuntu 12.04 LTSProcessor: Intel Core Duo Processor (2GHz or better)Memory: 4GB RAMHard Drive: 6GB free hard disk spaceGraphics: 1 GB - GLSL 1.3, OpenGL 2.1 compatible card - ATI Radeon HD 6750 / NVIDIA GeForce® 320 / NVIDIA® GeForce 9600 or higher,Additional Notes: Internet connection or LAN required for multiplayer 2013 Paradox Interactive™.
