In a recent Game Informer interview, executive producer on BioWare’s Mass Effect 3 Casey Hudson had a few things to say about the Citadel and endings in the final segment of the trilogy.
If you recall from the original Mass Effect, the Citadel was pretty large and has that quasi confusing transport shuttle system. Then is Mass Effect 2 it was considerably smaller and easier to travel around. Well in ME3 it is going to be huge. Those aspects of the Citadel, BioWare decided not to use in ME2 put made, will be added to the final installment. Don’t forget that that Citadel got quite the beat down at the end of the original Mass Effect.
"The Citadel is really big in this game. It's bigger than it's ever been, in terms of stuff to do. But yeah, it's those moments where there's fun and silly, neat stuff to explore. . . A kind of callback to the first Mass Effect."
The thing about Mass Effect 3 is that is the end of this trilogy. That is both huge and scary. Every aspect of the story they want to get across must absolutely be in this game. So a trend like the mission they took out of ME2 that they are putting in ME3, can’t happen since there won’t be a follow up game for this plot. Every story BioWare plans on conveying in the Shepard tale must be brought out in this game.
"This story arc is coming to an end with this game. That means the endings can be a lot more different. At this point we're taking into account so many decisions that you've made as a player and reflecting a lot of that stuff. It's not even in any way like the traditional game endings, where you can say how many endings there are or whether you got ending A, B, or C."
"It's more like there are some really obvious things that are different and then lots and lots of smaller things, lots of things about who lives and who dies, civilizations that rose and fell, all the way down to individual characters. That becomes the state of where you left your galaxy. The endings have a lot more sophistication and variety in them."
So from entire civilizations, to races, to individual characters – the endings will have it all. The Mass Effect series reigns in character development. We already know that Shepard is going to show signs of emotional uncertainty and doubt in possible failure, how will other characters react? How will story-arcs end? What will the fate of the Krogans be? What will happen to Tali? Will the Normandy remain intact?
In ME2, you have control over the fate of your crewmates. In Mass Effect 3 will you control the fate of entire races? Don’t forget the choices you’ve made in the last two games will affect the layout of the third. You killed off the rachni, didn’t you?
