Simlish is a fictional language featured in Maxis' Sim series of games. It debuted in SimCopter, and has been especially prominent in The Sims and The Sims 2. Simlish can also be heard in SimCity 4, but far less frequently. It also featured to an extent in the Maxis game Sid Meier's SimGolf. Designer Will Wright was conscious of the need for dialogue in the game, but thought that using a real language would make it sound too repetitive and would also be too costly to hire translators for world languages.

Initially, inspired by the Native American code talkers of WWII, Sims creator Will Wright and language expert Marc Gimbel suggested experimenting with the Navajo language to create Simlish. However ultimately they decided that Simlish worked best as a "language" made up of gibberish words that couldn't be translated, so that its meaning would be left open to the imagination of the player.



Probably one of the biggest features to the language is the recent featuring of many well known artisit, such as Natasha Beddingfield and Katy Perry to feature their songs on The Sims 2 Expansion. They have even gone as far as making music videos, which are viewed by millions on TheSims2.com and YouTube.
