I feel that that attitude is summed up in this post by David Gaider: http://dgaider.tumblr.com/post/52199343217/on-bringing-them-backhazabaza1 said:The Bioware approach of "Make every playthrough of one game essentially the same because people don't replay much" is bad enough but don't bring in these giant possibilities at the end of a game just to end up with "no fuck u lol nothing matters 4 u"
The TL;DR version is basically: "If character that died in a previous game only appears in a cameo, they are only 'sort of alive' and not 'alive alive'!" It pretty much comes across as a massive exercise in cognitive dissonance on his part, where he on hand says that he disregards player choices when writing a story, but on the other refuses to directly admitting that he ignores player choices, because "UR CHOICES MATTERS 4 REALZ!!1!" Also he apparently doesn't know what the word "cameo" means.
