questions regarding a slur in the sims 1 and 2

I think it really depends what country you're in (and what context you say it in) as to whether it's considered a slur. In the UK, "Gypsy" refers to a specific group of Romani people who have been living in the UK for centuries and is used in many official documents. So it does depend (and I'm not Romani myself). Anyway, just saying it's a grey area and depends. No idea if they'll change it.
