Irrational Games was founded in 1997 in Quincy, Massachusets by Ken Levine and several of his co-workers who have previously worked in other fields of the gaming industry. In the early years, Irrational was in many ways the sister company of Looking Glass Studios. They even exchanged their employees quite frequently and co-developed several projects (until LGS' closure in the spring of 2000). Over the years, Irrational Games have published a number of critically acclaimed and commercially succesful games - particularly the famous second installment of the System Shock series, SWAT 4 and the BioShock series (a spiritual successor to the original System Shock). In the early 2000s, the company opened up an Australian studio in Canberra.In January 2006, Irrational was bought by Take-Two Interactive and its name was changed to 2K Boston, with its Australian studio becoming 2K Australia. In 2010, however, Take-Two had a change of heart and allowed 2K Boston to adopt its former name again (seeing it as having better brand-recognition potential, given the succesful history of the developer). The Australian studio was eventually separated from Irrational and became a part of 2K Marin.Their most recent project was the very successful BioShock Infinite, the third installment of the series, which featured a brand new story and steampunkish enviroments.In February 2014, Levine announced on the company's website that he would "wind down Irrational Games as you know it" in an effort to focus on smaller, narratively driven games distributed digitally under the Take Two umbrella. That will entail eventually laying off most of the company and putting together a much leaner team of developers.Their website can be found here. They also have a podcast, called Irrational Behavior.
- System Shock II - Due to this being a collaboration with Looking Glass Studios, the game even uses the same basic engine as the first two Thief games.
- The Freedom Force series
- Tribes: Vengeance — A prequel to the Tribes series & sequel to the Starsiege series.
- SWAT 4 - The fourth installment of Sierra's tactical shooter series.
- The BioShock series
Tropes about this developer:
- The Dev Team Thinks of Everything: Irrational are well-known for their thoroughly in-depth gameplay mechanics that account for a lot of different situations the player can find himself in.
- Sophisticated as Hell: The below original pitch for Bioshock lists "scare the hell out of people" as one of the primary objectives. This is the only instance of swearing in the document, which is otherwise extremely professional.
- What Could Have Been: Lots of examples of this in the company's history. The Insider section of the studio's website gradually reveals a lot of them, mostly unrealized ideas or unused concept art.
- System Shock II was originally suppossed to feature a level set outside the ship, in the vacuum of space. It proved technically too demanding for the Dark Engine and the idea was eventually droped.
- The original pitch for BioShock had a very different setting, backstory and plot.
- Sometime in late 2005 and early 2006, Irrational Games used the existing SWAT 4 engine and assets as a proof-of-concept basis for their next game project, preemptively titled Division 9. It was supposed to be a Survival Horror shooter with a squad-based nature (much like SWAT 4) and set in... a noirish city after a mysterious Zombie Apocalypse. The project was eventually scrapped in favour of concentrating on BioShock. Three years later, Valve published a game with the same basic idea. Makes you wonder if Division 9 would've been similarly succesful years ago...
- Bioshock Infinite had gone through a lot of different concepts. Word of God even noted that the team had to cut "five or six games" worth of material from the final product.
- For Want of a Nail: Had an adventure game based on Star Trek: Voyager not been cancelled by Viacom when Looking Glass Studios was developing it in the mid 1990s, Ken Levine, Jonathan Chey and Rob Fermier might not have left the studio to found Irrational Games.
