To me, Simlish is the
primary language spoken by all Sims, but it is by no means the only language. I figure Sims can learn to speak English, French, Chinese, Khmer, German, Tagalog, Spanish, etc. if they wanted to; "human" languages thus exist in my game. I'm a bit more tolerant on English text in the game, although I still generally prefer Simlish text, if only because in all of my neighbourhoods Simlish is the primary and official language. Therefore, if I hang up an exit sign, or some safety/warning sign, I'd expect it to be written in Simlish so everyone can understand. EAxis actually did a fairly good job in their Sims games and in SimCity 4, where icons are used instead of text (The stop sign in
The Sims: Hot Date was an icon of a stop hand signal, and did not feature any text). Creators for The Sims generally use Simlish more often than creators for SimCity games;
really don't like seeing English in my SimCity 4 games.
