Hudson avoids spoilers, but suggests finishing the game for yourself and forming your own conclusions before reading his missive:
"For us and for you, Mass Effect 3 had to live up to a lot of expectations, not only for a great gaming experience, but for a resolution to the countless storylines and decisions you've made as a player since the journey began in 2007," Hudson writes. "So we designed Mass Effect 3 to be a series of endings to key plots and storylines, each culminating in scenes that show you the consequences of your actions. You then carry the knowledge of these consequences with you as you complete the final moments of your journey.
"We always intended that the scale of the conflict and the underlying theme of sacrifice would lead to a bittersweet ending -- to do otherwise would betray the agonizing decisions Shepard had to make along the way. Still, we wanted to give players the chance to experience an inspiring and uplifting ending; in a story where you face a hopeless struggle for basic survival, we see the final moments and imagery as offering victory and hope in the context of sacrifice and reflection."
Hudson stresses that the Mass Effect team takes fan feedback seriously and often incorporates it into the games directly, and says it is still listening to that response now. "Throughout the next year, we will support Mass Effect 3 by working on new content. And we'll keep listening, because your insights and constructive feedback will help determine what that content should be. This is not the last you'll hear of Commander Shepard."
