They've also announced an RPG in the works steeped in Norse mythology, and it's called Runemaster, which is "something new" for the Paradox Development Studio.
This will be the first RPG from Paradox's internal group which is traditionally neck deep in Europa Universalis, Victoria, Crusader Kings and Hearts of Iron.
Hearts of Iron IV
Hearts of Iron IV challenges players to face the brutal conflict of World War II in a multifaceted grand strategy game, where history can be fully relived or rewritten from the perspective of a global superpower attempting to change the world, or a small nation simply trying to survive. Strategy fans will discover the most authentic real-time simulation of World War II to date, with authentic historical figures battling on land, sea, and air with period-accurate armies, vehicles, and newly discovered weapons of mass destruction – along with plenty of diplomatic and trade tactics.
Runemaster is an RPG set in a fantasy realm based in the rich, majestic traditions of Norse mythology, casting each player in the role of a unique champion in a time of chaotic upheaval. Procedural maps and quests will ensure that no two playthroughs are identical, allowing players to tell a saga that is uniquely their own. Explore vast vistas through the six worlds of Norse myth, command troops in tactical combat, and define your champion through the choices they make.
Paradox has already announced at their Paradox Convention in Miami that Crusader Kings II will be expanding its map by 50% with over 300 new provinces with the new Rise of India expansion. Europa Universalis IV is also expanding again with the Wealth Nations add-on that improves and expands upon national trade.
