AfterElton is reporting that The Sims 3, released Tuesday, has included gay marriage in it's universe:

After a week of game time, I was able to get a male couple to plan a wedding party and tie the knot.

It may seem like a small step for a game series that has always been LGB-inclusive, but games that treat gay people equally are still pretty rare. Homophobia is still sadly common among video game communities and, worse, some companies' attempts to deal with anti-gay harassment have ended up being even more repressive to queer players.
