Information about this game has appeared in the CDR database
Paradox Interactive will bring Europa Universalis IV to the Linux platform, along with the other OSes.At least this is what we have been led to believe by the CDR entry. Europa Universalis IV will be returning in autumn after a long hiatus of the franchise.
Europa Universalis IV will feature some new options, such as the Monarch Power, a lush topographical map in full 3D, trade route control, and much more.
The information about the Linux version is taken from the CDR database and by no means is it completely certain. The CDR Database is a record of data that describes every Steam game and subscription provided by Valve for the Steam service.
Usually, the new entries in the Steam database are first visible in the CDR Database before their official launch.
