This is a DLC for Stellaris

About this game:
Utopia is the first major expansion for Stellaris, the critically acclaimed science fiction grand strategy game from Paradox Development Studio. As the title suggests, Utopia gives you new tools to develop your galactic empire and keep your people (or birdfolk or talking mushrooms) happy. Push your species further out into the galaxy with new bonuses for rapid exploration or stay closer to home before striking out against all who would challenge you.
