That design document predated the decision to exclude gay relationships in the game. Its pages described a web of social interactions, in which every kind of romantic relationship was permitted. That week, Barrett confounded the expectations of his disbelieving boss. He successfully wrote the basic code for social interactions, including same-sex relationships. 

“In hindsight, I probably should have questioned the design,” Barrett, who is gay, said. “But the design felt right, so I just implemented it. Later, Will Wright stopped by my desk,” Barrett said. “He told me that liked the social interactions, and that he was glad to see that same-sex support was back in the game.” Nobody on the team questioned Barrett’s work. “They just pretty much ignored it,” he said. “After a while, everyone was just used to the design being there. It was widely expected that E.A. would just kill it, anyway.”

In early 1999, before E.A. had a chance to kill the design, Barrett was asked to create a demo of the game to be shown at E3. The demo would consist of three scenes from the game. These were to be so-called on-rails scenes—not a true, live simulation but one that was preplanned, and which would shake out the same way each time it was played, in order to show the game in its best light. 

One of the scenes was a wedding between two Sims characters. “I had run out of time before E3, and there were so many Sims attending the wedding that I didn’t have time to put them all on rails,” Barrett said.

On the first day of the show, the game’s producers, Kana Ryan and Chris Trottier, watched in disbelief as two of the female Sims attending the virtual wedding leaned in and began to passionately kiss. They had, during the live simulation, fallen in love.

TIL i learned that the team behind The Sims had originally decided to leave same-sex relationships out of the game until a newbie on the team by the name of Patrick J. Barrett III coded all basic interactions of the game due to one of his senior team members being on vacation, TIL Barrett unknowingly had been given an old design document and everyone just assumed someone else had reversed their previous decision and rolled with it, and TIL that all that plus a rushed demo led to the team’s presentation at that year’s E3 featuring an unplanned lesbian kiss
