One Star Wars: Knights of the Old Republic dev spent an entire day scrubbing through the films in search of a specific word that Lucasfilm said the RPG team wasn't allowed to use.
In an interview with FRVR, BioWare's Mark Darrah - who didn't work on KOTOR but was active at the studio and eventually helped make MMO The Old Republic - said that Lucasfilm had a specific problem with the RPG's language. Specifically, they didn't like the use of the word 'damn', which they claimed wasn't something that a Star Wars character would say.
