- The Sims Programmer Patrick J. Barrett III

In a new interview with The New Yorker, a programmer on the original 2000 version of the The Sims recounts how he mistakenly same-sex-marriage in the game, and why it stuck.

Programmer Patrick J. Barrett III was handed the task of implementing relationships in the game -- but was also given an outdated design doc that allowed for same-sex unions, which the team had decided might be too controversial to implement.

"In hindsight, I probably should have questioned the design," Barrett told The New Yorker. "But the design felt right, so I just implemented it." His work was approved by SimCity creator Will Wright, Barrett says, which ended the conversation: “He told me that liked the social interactions, and that he was glad to see that same-sex support was back in the game."

The system came to light at E3 1999, when EA publicly showcased the game for the first time. Two female Sims engaged in a kiss during a presentation: "You might say that they stole the show," Barrett says. He'd expected EA to kill the feature, but the publisher let it slide.
