Core mechanics allow player-driven same-sex romantic interactions, 'Joined Union' ceremonies for same-gender couples, fluid gender preferences influenced by gameplay, and same-sex adoption, all implemented as part of the sandbox life simulation that treats relationships as one optional facet among many. These features originated in the original design to reflect real human variety without labels, story mandates, or activist framing.

Character creation remains strictly binary male/female with no pronoun selection, body-type swaps, or nonbinary options. Screenshots confirm classic pre-made Sims and household scenes with incidental visual variety but no highlighted identity politics.

No developer statements, patch notes, or marketing for the Legacy Collection reference DEI, consultancy firms, or contemporary social justice themes. Recent external ownership debates around EA do not alter the fixed 2004 content.
