Tartosa is boring, and commentary about same-y worlds in general

Selvadorada and Strangerville have the most perceivable personality IMO. The other worlds need to be heavily edited by us players to make it feel cultured but we're limited by sims themselves not having cultural traits.

It helps that the townies in Strangerville are mostly military people (and a lot of handsome ones) and the ones in Selvadorada dance differently and are usually dressed appropriately.
