Stellaris was developed by
Paradox Development Studios and published by
Paradox Interactive. The game uses the same
Clausewitz Engine that the studio has used since
Europa Universalis III in 2007 albeit with some modifications, such as the usage of
physically based rendering (PBR). The game was presented at
Gamescom in August 2015. Director Henrik Fahraeus describes his influences as "one third
Star Control 2, one third
Master of Orion 2 and one third
Europa Universalis IV", to "create a strategy game with particular focus on exploration and expansion". The team also referenced
Star Control II with several character concepts and personalities, including alien races who resemble birds, mushrooms, and gas clouds. Stellaris was released to the public on May 9, 2016. After launch, the developers confirmed that there would be a number of expansion packs, as well as free updates to address bugs and introduce new gameplay features. The updates were named after famous science fiction writers, including
Stanisław Lem,
Arthur C. Clarke,
Isaac Asimov,
Robert A. Heinlein,
Iain Banks,
Douglas Adams,
Ray Bradbury,
Karel Čapek,
Pierre Boulle,
C. J. Cherryh,
Larry Niven,
Ursula K. Le Guin,
Gene Wolfe,
Tanith Lee, and
Mary Shelley, until 2022, when they began to take the names of constellations starting with 3.3, "
Libra". The game is accompanied by free patches, which may adjust existing mechanics or add new ones in the same theme as the expansions. The first major patch arrived on May 24, shortly after the game's release, featuring numerous improvements to the AI, as well as an additional playable race. The 2.0 patch (Cherryh), released in February 2018, revamps a significant amount of game mechanics, even for players who have not purchased the corresponding "Apocalypse" DLC. The 2.1 (Niven) update, released alongside the "Distant Stars" DLC in May, revamped the base game play loop and added more quality-of-life features. The 2.2 (Le Guin) update was released in December, along with the "Megacorp" DLC, and revamped how planets are organized. The 3.0 (
Dick) update was released in April 2021, coinciding with the release of the "Nemesis" DLC. Minor releases have continued through 2022 with 3.5 being released September 2022. There have been plenty of story packs and species packs that have been released, each adding a new in game events, origins, empire types, species, traits, civic, and ascension perks. Plantoids Species Pack dropped August 4, 2016 being the first, and the latest being Astral Planes, released November 16, 2023.
Paradox ported the game to consoles. The PlayStation 4 and Xbox One versions of
Stellaris were released on February 26, 2019, as
Stellaris: Console Edition. A version of the game optimized for Xbox Series X/S released on March 25, 2021.
Expansions and DLCs A number of
DLCs have been released for the game. All are optional and may be applied to the base game in any combination. The largest DLCs come in the form of expansions, which significantly alter the mechanics and features of the game. There are also story packs (which add new events and minor mechanics) and species packs (which add new species, with accompanying audio, visuals and mechanics). ==Reception==
