BioWare has made some remarkable promises for the PS3 version of Mass Effect 2, detailing that it would be as good or better than any other version of the game. Jesse Houston, producer for the PS3 version of Mass Effect 2, detailed that it was possible using the Mass Effect 3 engine.

“We’ve actually created the engine for Mass Effect 3 and use that to make Mass Effect 2 PS3, said Houston. So we took the content and the story and all the other assets that made up Mass Effect 2 and we put them in the Mass Effect 3 engine. And that s what we are actually delivering.”
