Mass Effect had three different romance options and the second game in the series had nine (to varying degrees). Because of this, Mass Effect 3 won’t focus on new romances, instead looking exclusively at existing relationships and possible love triangles.

In this one, we don t really have new characters that are part of the romance stuff in the way that we did in Mass Effect 2, where we introduced a lot of characters, said executive producer on the Mass Effect series, Casey Hudson. So this is more about how you, if you’re a new player, how you start these romances with the existing characters. If you’ve had relationships with previous characters, then it’s your opportunity to resolve those. And again, it s in the context of a World War II -type setting, so you don’t really know if you’re going to survive, or what kind of a world is going to live beyond the story. So it’s kind of that situation.

But we also have some interesting things happening, where you’ve got Ashley and Kaiden from the first game, you’ve got Liara, and there s sort of a love triangle there. And then we gave people a bunch of new characters, he continued. People said ‘Well, I just want my Mass Effect 1 characters, and I’m not interested in any of these characters.’ But then a lot of people had romances with those characters, and now the fun is bringing back some of those characters from Mass Effect 1 and putting them back in the mix, and looking at what you did in Mass Effect 2 and bringing some interesting scenarios around those things.
