I would like information about the game Svea Rike?

Much of the gameplay information used by the engine is contained in uncompressed text and bitmap graphic files. The ability to freely edit these files has allowed an active modding community to develop. The Paradox forum is highly active and provides a way for players and modders alike to collaborate and improve gameplay and develop complex new scenarios for each title. The Paradox game developers are also active in the forums, and incorporate ideas and even contributions from the gameplaying community in ways that many larger gameing companies do not. Europa Universalis: Crown of the North included 2 user created scenarios (the unhistorical "Independent Europe Scenario", and the expanded "Alternative Grand Campaign") that came directly from forum contributors, rather than by game developers. Also, the upcomming Europa Universalis III is being developed in close collaboration with experienced players of the earlier titles through discussions on the forum.
